   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * If realloc_if_needed is true (the default), it is assumed that the buffer does *not* have enough padding,
   * and it is copied into an enlarged temporary buffer before parsing. Thus the following is safe:
   *
   *   const char *json      = R"({"key":"value"})";
   *   const size_t json_len = std::strlen(json);
   *   simdjson::dom::parser parser;
   *   simdjson::dom::element element = parser.parse(json, json_len);
   *
   * If you set realloc_if_needed to false (e.g., parser.parse(json, json_len, false)),
   * you must provide a buffer with at least SIMDJSON_PADDING extra bytes at the end.
   * The benefit of setting realloc_if_needed to false is that you avoid a temporary
   * memory allocation and a copy.
   *
   * The padded bytes may be read. It is not important how you initialize
   * these bytes though we recommend a sensible default like null character values or spaces.
   * For example, the following low-level code is safe:
   *
   *   const char *json      = R"({"key":"value"})";
   *   const size_t json_len = std::strlen(json);
   *   std::unique_ptr<char[]> padded_json_copy{new char[json_len + SIMDJSON_PADDING]};
   *   std::memcpy(padded_json_copy.get(), json, json_len);
   *   std::memset(padded_json_copy.get() + json_len, '\0', SIMDJSON_PADDING);
   *   simdjson::dom::parser parser;
   *   simdjson::dom::element element = parser.parse(padded_json_copy.get(), json_len, false);
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than len, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The JSON to parse. Must have at least len + SIMDJSON_PADDING allocated bytes, unless
   *            realloc_if_needed is true.
   * @param len The length of the JSON.
   * @param realloc_if_needed Whether to reallocate and enlarge the JSON buffer to add padding.
   * @return An element pointing at the root of the document, or an error:
   *         - MEMALLOC if realloc_if_needed is true or the parser does not have enough capacity,
   *           and memory allocation fails.
   *         - CAPACITY if the parser does not have enough capacity and len > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the

   *   }
   *
   * The file is loaded in memory and can be safely deleted after the `parser.load_many(path)`
   * function has returned. The memory is held by the `parser` instance.
   *
   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   * And, possibly, no document many have been parsed when the `parser.load_many(path)` function
   * returned.
   *
   * ### Format
   *
   * The file must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * Documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with whitespace.
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excesively small values may impact negatively the
   * performance.
   *
   * ### Error Handling
   *
   * All errors are returned during iteration: if there is a global error such as memory allocation,
   * it will be yielded as the first result. Iteration always stops after the first error.
   *
   * As with all other simdjson methods, non-exception error handling is readily available through
   * the same interface, requiring you to check the error before using the document:
   *
   *   dom::parser parser;
   *   dom::document_stream docs;
   *   auto error = parser.load_many(path).get(docs);
   *   if (error) { cerr << error << endl; exit(1); }
   *   for (auto doc : docs) {
   *     std::string_view title;
   *     if ((error = doc["title"].get(title)) { cerr << error << endl; exit(1); }
   *     cout << title << endl;
   *   }
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param path File name pointing at the concatenated JSON to parse.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.

  inline simdjson_result<document_stream> load_many(const std::string &path, size_t batch_size = dom::DEFAULT_BATCH_SIZE) noexcept;

  /**
   * Parse a buffer containing many JSON documents.
   *
   *   dom::parser parser;
   *   for (element doc : parser.parse_many(buf, len)) {
   *     cout << std::string(doc["title"]) << endl;
   *   }
   *
   * No copy of the input buffer is made.
   *
   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   * And, possibly, no document many have been parsed when the `parser.load_many(path)` function
   * returned.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop. In particular, the following is unsafe and will not compile:
   *
   *   auto docs = parser.parse_many("[\"temporary data\"]"_padded);
   *   // here the string "[\"temporary data\"]" may no longer exist in memory
   *   // the parser instance may not have even accessed the input yet
   *   for (element doc : docs) {
   *     cout << std::string(doc["title"]) << endl;
   *   }
   *
   * The following is safe:
   *
   *   auto json = "[\"temporary data\"]"_padded;
   *   auto docs = parser.parse_many(json);
   *   for (element doc : docs) {
   *     cout << std::string(doc["title"]) << endl;
   *   }
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with whitespace.
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excesively small values may impact negatively the
   * performance.
   *
   * ### Error Handling
   *
   * All errors are returned during iteration: if there is a global error such as memory allocation,
   * it will be yielded as the first result. Iteration always stops after the first error.
   *
   * As with all other simdjson methods, non-exception error handling is readily available through
   * the same interface, requiring you to check the error before using the document:
   *
   *   dom::parser parser;
   *   dom::document_stream docs;
   *   auto error = parser.load_many(path).get(docs);
   *   if (error) { cerr << error << endl; exit(1); }
   *   for (auto doc : docs) {
   *     std::string_view title;
   *     if ((error = doc["title"].get(title)) { cerr << error << endl; exit(1); }
   *     cout << title << endl;
   *   }
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse. Must have at least len + SIMDJSON_PADDING allocated bytes.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

/**
 * Design notes:
 * Instead of constructing a string_view and then comparing it with a
 * user-provided strings, it is probably more performant to have dedicated
 * functions taking as a parameter the string we want to compare against
 * and return true when they are equal. That avoids the creation of a temporary
 * std::string_view. Though it is possible for the compiler to avoid entirely
 * any overhead due to string_view, relying too much on compiler magic is
 * problematic: compiler magic sometimes fail, and then what do you do?
 * Also, enticing users to rely on high-performance function is probably better
 * on the long run.

 * or x86intrin.h. However, when compiling with clang
 * under Windows (i.e., when _MSC_VER is set), these headers
 * only get included *if* the corresponding features are detected
 * from macros:
 * e.g., if __AVX2__ is set... in turn,  we normally set these
 * macros by compiling against the corresponding architecture
 * (e.g., arch:AVX2, -mavx2, etc.) which compiles the whole
 * software with these advanced instructions. In simdjson, we
 * want to compile the whole program for a generic target,
 * and only target our specific kernels. As a workaround,
 * we directly include the needed headers. These headers would
 * normally guard against such usage, but we carefully included
 * <x86intrin.h>  (or <intrin.h>) before, so the headers
 * are fooled.

 * make_uint8x16_t initializes a SIMD register (uint8x16_t).
 * This is needed because, incredibly, the syntax uint8x16_t x = {1,2,3...}
 * is not recognized under Visual Studio! This is a workaround.
 * Using a std::initializer_list<uint8_t>  as a parameter resulted in
 * inefficient code. With the current approach, if the parameters are
 * compile-time constants,
 * GNU GCC compiles it to ldr, the same as uint8x16_t x = {1,2,3...}.
 * You should not use this function except for compile-time constants:
 * it is not efficient.

   *
   * ({"globals":{"a":{"shadowable":[}}}})
   *
   * If the user thinks it is a Boolean and asks for it, then we check the '[',

   * we are left pointing at '}' right after a '['. And we have not yet reported
   * an error, only that we do not have a Boolean.
   *
   * If, instead, you just stand your ground until it is content that you know, then
   * you will only even move beyond the '[' if the user tells you that you have an
   * array. So you will be at the '}' character inside the array and, hopefully, you
   * will then catch the error because an array cannot start with '}', but the code
   * processing Boolean values does not know this.
   *
   * So the contract is: first call 'peek_...' and then call 'advance_...' only
   * if you have determined that it is a type you can handle.

 * A string escaped per JSON rules, terminated with quote ("). They are used to represent
 * unescaped keys inside JSON documents.
 *
 * (In other words, a pointer to the beginning of a string, just after the start quote, inside a
 * JSON file.)
 *
 * This class is deliberately simplistic and has little functionality. You can
 * compare a raw_json_string instance with an unescaped C string, but
 * that is nearly all you can do.
 *
 * The raw_json_string is unescaped. If you wish to write an unescaped version of it to your own
 * buffer, you may do so using the parser.unescape(string, buff) method, using an ondemand::parser
 * instance. Doing so requires you to have a sufficiently large buffer.
 *
 * The raw_json_string instances originate typically from field instance which in turn represent
 * key-value pairs from object instances. From a field instance, you get the raw_json_string
 * instance by calling key(). You can, if you want a more usable string_view instance, call
 * the unescaped_key() method on the field instance. You may also create a raw_json_string from
 * any other string value, with the value.get_raw_json_string() method. Again, you can get
 * a more usable string_view instance by calling get_string().

   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop.
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by ASCII whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. Documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with ASCII whitespace.
   *
   * The characters inside a JSON document, and between JSON documents, must be valid Unicode (UTF-8).
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excessively small values may impact negatively the
   * performance.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @param allow_comma_separated (defaults on false) This allows a mode where the documents are
   *                   separated by commas instead of whitespace. It comes with a performance
   *                   penalty because the entire document is indexed at once (and the document must be
   *                   less than 4 GB), and there is no multithreading. In this mode, the batch_size parameter
   *                   is effectively ignored, as it is set to at least the document size.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

// ### Live States
//
// While iterating or looking up values, depth >= iter->depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the array is first found and the iterator is just past the `{`.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the `,` before the next value (or `]`). In this state,
//   depth == iter->depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter->depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter->depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the array iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet element may be missing or not be an
//   array--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter->depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between elements,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter->depth == depth, and at_start == false.
//
// ## Terminal State
//
// The terminal state has iter->depth < depth. at_start is always false.
//
// - Finished: When we have reached a `]` or have reported an error, we are finished. We signal this
//   by decrementing depth. In this state, iter->depth < depth, at_start == false, and
//   error == SUCCESS.

       *
       * {"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]  [15,  11,   12, 13]  [154,  110,   112, 1311]
       *
       * Say you process the following window...
       *
       * '{"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]'
       *
       * When you do so, the json_iterator has a pointer at the beginning of the memory region
       * (pointing at the beginning of '{"z"...'.
       *
       * When you move to the window that starts at...
       *
       * '[7,  10,   9]  [15,  11,   12, 13] ...
       *
       * then it is not sufficient to just run stage 1. You also need to re-anchor the
       * json_iterator so that it believes we are starting at '[7,  10,   9]...'.
       *
       * Under the DOM front-end, this gets done automatically because the parser owns
       * the pointer the data, and when you call stage1 and then stage2 on the same
       * parser, then stage2 will run on the pointer acquired by stage1.
       *
       * That is, stage1 calls "this->buf = _buf" so the parser remembers the buffer that
       * we used. But json_iterator has no callback when stage1 is called on the parser.
       * In fact, I think that the parser is unaware of json_iterator.
       *

// ### Live States
//
// While iterating or looking up values, depth >= iter.depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the object is first found and the iterator is just past the {.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the , or } before the next value. In this state,
//   depth == iter.depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
//   object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State
//
// The terminal state has iter.depth < depth. at_start is always false.
//
// - Finished: When we have reached a }, we are finished. We signal this by decrementing depth.
//   In this state, iter.depth < depth, at_start == false, and error == SUCCESS.

   * "shadowable" in the following example...
   *
   * ({"globals":{"a":{"shadowable":[}}}})
   *
   * If the user thinks it is a Boolean and asks for it, then we check the '[',

   * we are left pointing at '}' right after a '['. And we have not yet reported
   * an error, only that we do not have a Boolean.
   *
   * If, instead, you just stand your ground until it is content that you know, then
   * you will only even move beyond the '[' if the user tells you that you have an
   * array. So you will be at the '}' character inside the array and, hopefully, you
   * will then catch the error because an array cannot start with '}', but the code
   * processing Boolean values does not know this.
   *
   * So the contract is: first call 'peek_...' and then call 'advance_...' only

   *
   * ### IMPORTANT: Buffer Lifetime
   *
   * Because parsing is done while you iterate, you *must* keep the JSON buffer around at least as
   * long as the document iteration.
   *
   * ### IMPORTANT: Document Lifetime
   *
   * Only one iteration at a time can happen per parser, and the parser *must* be kept alive during
   * iteration to ensure intermediate buffers can be accessed. Any document must be destroyed before
   * you call parse() again or destroy the parser.
   *
   * The ondemand::document instance holds the iterator. The document must remain in scope
   * while you are accessing instances of ondemand::value, ondemand::object, ondemand::array.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * @param json The JSON to parse.
   *
   * @return The iterator, or an error:
   *         - INSUFFICIENT_PADDING if the input has less than SIMDJSON_PADDING extra bytes.
   *         - MEMALLOC if realloc_if_needed the parser does not have enough capacity, and memory
   *           allocation fails.
   *         - EMPTY if the document is all whitespace.
   *         - UTF8_ERROR if the document is not valid UTF-8.
   *         - UNESCAPED_CHARS if a string contains control characters that must be escaped
   *         - UNCLOSED_STRING if there is an unclosed string in the document.

  /**
   * Parse a buffer containing many JSON documents.

   *   ondemand::parser parser;
   *   ondemand::document_stream docs = parser.iterate_many(json);
   *   for (auto & doc : docs) {
   *     std::cout << doc["foo"] << std::endl;
   *   }
   *   // Prints 1 2 3
   *
   * No copy of the input buffer is made.
   *
   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop.
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by ASCII whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. Documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with ASCII whitespace.
   *
   * The characters inside a JSON document, and between JSON documents, must be valid Unicode (UTF-8).
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excessively small values may impact negatively the
   * performance.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @param allow_comma_separated (defaults on false) This allows a mode where the documents are
   *                   separated by commas instead of whitespace. It comes with a performance
   *                   penalty because the entire document is indexed at once (and the document must be
   *                   less than 4 GB), and there is no multithreading. In this mode, the batch_size parameter
   *                   is effectively ignored, as it is set to at least the document size.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

// ### Live States
//
// While iterating or looking up values, depth >= iter->depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the array is first found and the iterator is just past the `{`.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the `,` before the next value (or `]`). In this state,
//   depth == iter->depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter->depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter->depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the array iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet element may be missing or not be an
//   array--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter->depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between elements,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter->depth == depth, and at_start == false.
//
// ## Terminal State
//
// The terminal state has iter->depth < depth. at_start is always false.
//
// - Finished: When we have reached a `]` or have reported an error, we are finished. We signal this
//   by decrementing depth. In this state, iter->depth < depth, at_start == false, and
//   error == SUCCESS.

       * '{"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]'
       *

// ### Live States
//
// While iterating or looking up values, depth >= iter.depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the object is first found and the iterator is just past the {.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the , or } before the next value. In this state,
//   depth == iter.depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
//   object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State
//
// The terminal state has iter.depth < depth. at_start is always false.
//
// - Finished: When we have reached a }, we are finished. We signal this by decrementing depth.
//   In this state, iter.depth < depth, at_start == false, and error == SUCCESS.

   *
   * ({"globals":{"a":{"shadowable":[}}}})
   *
   * If the user thinks it is a Boolean and asks for it, then we check the '[',

   * we are left pointing at '}' right after a '['. And we have not yet reported
   * an error, only that we do not have a Boolean.
   *
   * If, instead, you just stand your ground until it is content that you know, then
   * you will only even move beyond the '[' if the user tells you that you have an
   * array. So you will be at the '}' character inside the array and, hopefully, you
   * will then catch the error because an array cannot start with '}', but the code
   * processing Boolean values does not know this.
   *
   * So the contract is: first call 'peek_...' and then call 'advance_...' only

   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop.
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by ASCII whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. Documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with ASCII whitespace.
   *
   * The characters inside a JSON document, and between JSON documents, must be valid Unicode (UTF-8).
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excessively small values may impact negatively the
   * performance.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @param allow_comma_separated (defaults on false) This allows a mode where the documents are
   *                   separated by commas instead of whitespace. It comes with a performance
   *                   penalty because the entire document is indexed at once (and the document must be
   *                   less than 4 GB), and there is no multithreading. In this mode, the batch_size parameter
   *                   is effectively ignored, as it is set to at least the document size.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

  /**
   * Look up a field by name on an object, without regard to key order.
   *
   * **Performance Notes:** This is a bit less performant than find_field(), though its effect varies
   * and often appears negligible. It starts out normally, starting out at the last field; but if
   * the field is not found, it scans from the beginning of the object to see if it missed it. That
   * missing case has a non-cache-friendly bump and lots of extra scanning, especially if the object
   * in question is large. The fact that the extra code is there also bumps the executable size.
   *
   * It is the default, however, because it would be highly surprising (and hard to debug) if the
   * default behavior failed to look up a field just because it was in the wrong order--and many
   * APIs assume this. Therefore, you must be explicit if you want to treat objects as out of order.
   *
   * Use find_field() if you are sure fields will be in order (or are willing to treat it as if the
   * field wasn't there when they aren't).
   *
   * If you have multiple fields with a matching key ({"x": 1,  "x": 1}) be mindful
   * that only one field is returned.
   *
   * You must consume the fields on an object one at a time. A request for a new key
   * invalidates previous field values: it makes them unsafe. The value instance you get
   * from  `content["bids"]` becomes invalid when you call `content["asks"]`. The array
   * given by content["bids"].get_array() should not be accessed after you have called
   * content["asks"].get_array(). You can detect such mistakes by first compiling and running
   * the code in Debug mode (or with the macro `SIMDJSON_DEVELOPMENT_CHECKS` set to 1): an
   * OUT_OF_ORDER_ITERATION error is generated.
   *
   * You are expected to access keys only once. You should access the value corresponding to a key
   * a single time. Doing object["mykey"].to_string() and then again object["mykey"].to_string() is an error.
   *
   * @param key The key to look up.
   * @returns The value of the field, or NO_SUCH_FIELD if the field is not in the object.

// ### Live States
//
// While iterating or looking up values, depth >= iter->depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the array is first found and the iterator is just past the `{`.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the `,` before the next value (or `]`). In this state,
//   depth == iter->depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter->depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter->depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the array iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet element may be missing or not be an
//   array--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter->depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between elements,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter->depth == depth, and at_start == false.
//
// ## Terminal State
//
// The terminal state has iter->depth < depth. at_start is always false.
//
// - Finished: When we have reached a `]` or have reported an error, we are finished. We signal this
//   by decrementing depth. In this state, iter->depth < depth, at_start == false, and
//   error == SUCCESS.

       * {"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]  [15,  11,   12, 13]  [154,  110,   112, 1311]
       *
       * Say you process the following window...
       *
       * '{"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]'
       *
       * When you do so, the json_iterator has a pointer at the beginning of the memory region
       * (pointing at the beginning of '{"z"...'.
       *
       * When you move to the window that starts at...
       *
       * '[7,  10,   9]  [15,  11,   12, 13] ...
       *
       * then it is not sufficient to just run stage 1. You also need to re-anchor the
       * json_iterator so that it believes we are starting at '[7,  10,   9]...'.
       *
       * Under the DOM front-end, this gets done automatically because the parser owns
       * the pointer the data, and when you call stage1 and then stage2 on the same
       * parser, then stage2 will run on the pointer acquired by stage1.
       *
       * That is, stage1 calls "this->buf = _buf" so the parser remembers the buffer that
       * we used. But json_iterator has no callback when stage1 is called on the parser.
       * In fact, I think that the parser is unaware of json_iterator.
       *

// ### Live States
//
// While iterating or looking up values, depth >= iter.depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the object is first found and the iterator is just past the {.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the , or } before the next value. In this state,
//   depth == iter.depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
//   object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State
//
// The terminal state has iter.depth < depth. at_start is always false.
//
// - Finished: When we have reached a }, we are finished. We signal this by decrementing depth.
//   In this state, iter.depth < depth, at_start == false, and error == SUCCESS.

   *
   * ({"globals":{"a":{"shadowable":[}}}})
   *
   * If the user thinks it is a Boolean and asks for it, then we check the '[',

   * we are left pointing at '}' right after a '['. And we have not yet reported
   * an error, only that we do not have a Boolean.
   *
   * If, instead, you just stand your ground until it is content that you know, then
   * you will only even move beyond the '[' if the user tells you that you have an
   * array. So you will be at the '}' character inside the array and, hopefully, you
   * will then catch the error because an array cannot start with '}', but the code
   * processing Boolean values does not know this.
   *
   * So the contract is: first call 'peek_...' and then call 'advance_...' only

   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop.
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by ASCII whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. Documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with ASCII whitespace.
   *
   * The characters inside a JSON document, and between JSON documents, must be valid Unicode (UTF-8).
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excessively small values may impact negatively the
   * performance.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @param allow_comma_separated (defaults on false) This allows a mode where the documents are
   *                   separated by commas instead of whitespace. It comes with a performance
   *                   penalty because the entire document is indexed at once (and the document must be
   *                   less than 4 GB), and there is no multithreading. In this mode, the batch_size parameter
   *                   is effectively ignored, as it is set to at least the document size.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

   * default behavior failed to look up a field just because it was in the wrong order--and many
   * APIs assume this. Therefore, you must be explicit if you want to treat objects as out of order.
   *
   * Use find_field() if you are sure fields will be in order (or are willing to treat it as if the
   * field wasn't there when they aren't).
   *
   * If you have multiple fields with a matching key ({"x": 1,  "x": 1}) be mindful
   * that only one field is returned.
   *
   * You must consume the fields on an object one at a time. A request for a new key
   * invalidates previous field values: it makes them unsafe. The value instance you get
   * from  `content["bids"]` becomes invalid when you call `content["asks"]`. The array
   * given by content["bids"].get_array() should not be accessed after you have called
   * content["asks"].get_array(). You can detect such mistakes by first compiling and running
   * the code in Debug mode (or with the macro `SIMDJSON_DEVELOPMENT_CHECKS` set to 1): an
   * OUT_OF_ORDER_ITERATION error is generated.
   *
   * You are expected to access keys only once. You should access the value corresponding to a key
   * a single time. Doing object["mykey"].to_string() and then again object["mykey"].to_string() is an error.
   *
   * @param key The key to look up.
   * @returns The value of the field, or NO_SUCH_FIELD if the field is not in the object.

// ### Live States
//
// While iterating or looking up values, depth >= iter->depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the array is first found and the iterator is just past the `{`.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the `,` before the next value (or `]`). In this state,
//   depth == iter->depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter->depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter->depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the array iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet element may be missing or not be an
//   array--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter->depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between elements,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter->depth == depth, and at_start == false.
//
// ## Terminal State
//
// The terminal state has iter->depth < depth. at_start is always false.
//
// - Finished: When we have reached a `]` or have reported an error, we are finished. We signal this
//   by decrementing depth. In this state, iter->depth < depth, at_start == false, and
//   error == SUCCESS.

       * {"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]  [15,  11,   12, 13]  [154,  110,   112, 1311]
       *
       * Say you process the following window...
       *
       * '{"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]'
       *
       * When you do so, the json_iterator has a pointer at the beginning of the memory region
       * (pointing at the beginning of '{"z"...'.
       *
       * When you move to the window that starts at...
       *
       * '[7,  10,   9]  [15,  11,   12, 13] ...
       *
       * then it is not sufficient to just run stage 1. You also need to re-anchor the
       * json_iterator so that it believes we are starting at '[7,  10,   9]...'.
       *
       * Under the DOM front-end, this gets done automatically because the parser owns
       * the pointer the data, and when you call stage1 and then stage2 on the same
       * parser, then stage2 will run on the pointer acquired by stage1.
       *
       * That is, stage1 calls "this->buf = _buf" so the parser remembers the buffer that
       * we used. But json_iterator has no callback when stage1 is called on the parser.
       * In fact, I think that the parser is unaware of json_iterator.
       *

// ### Live States
//
// While iterating or looking up values, depth >= iter.depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the object is first found and the iterator is just past the {.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the , or } before the next value. In this state,
//   depth == iter.depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
//   object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State
//
// The terminal state has iter.depth < depth. at_start is always false.
//
// - Finished: When we have reached a }, we are finished. We signal this by decrementing depth.
//   In this state, iter.depth < depth, at_start == false, and error == SUCCESS.

   * We used to unconditionally advance. But this made reasoning about our
   * current state difficult.
   * Suppose you always advance. Look at the 'value' matching the key
   * "shadowable" in the following example...
   *
   * ({"globals":{"a":{"shadowable":[}}}})
   *
   * If the user thinks it is a Boolean and asks for it, then we check the '[',
   * decide it is not a Boolean, but still move into the next character ('}'). Now
   * we are left pointing at '}' right after a '['. And we have not yet reported
   * an error, only that we do not have a Boolean.
   *
   * If, instead, you just stand your ground until it is content that you know, then
   * you will only even move beyond the '[' if the user tells you that you have an
   * array. So you will be at the '}' character inside the array and, hopefully, you
   * will then catch the error because an array cannot start with '}', but the code
   * processing Boolean values does not know this.
   *
   * So the contract is: first call 'peek_...' and then call 'advance_...' only
   * if you have determined that it is a type you can handle.
   *
   * Unfortunately, it makes the code more verbose, longer and maybe more error prone.

   *   }
   *   // Prints 1 2 3
   *
   * No copy of the input buffer is made.
   *
   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop.
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by ASCII whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. Documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with ASCII whitespace.
   *
   * The characters inside a JSON document, and between JSON documents, must be valid Unicode (UTF-8).
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excessively small values may impact negatively the
   * performance.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @param allow_comma_separated (defaults on false) This allows a mode where the documents are
   *                   separated by commas instead of whitespace. It comes with a performance
   *                   penalty because the entire document is indexed at once (and the document must be
   *                   less than 4 GB), and there is no multithreading. In this mode, the batch_size parameter
   *                   is effectively ignored, as it is set to at least the document size.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

   * Look up a field by name on an object, without regard to key order.
   *
   * **Performance Notes:** This is a bit less performant than find_field(), though its effect varies
   * and often appears negligible. It starts out normally, starting out at the last field; but if
   * the field is not found, it scans from the beginning of the object to see if it missed it. That
   * missing case has a non-cache-friendly bump and lots of extra scanning, especially if the object
   * in question is large. The fact that the extra code is there also bumps the executable size.
   *
   * It is the default, however, because it would be highly surprising (and hard to debug) if the
   * default behavior failed to look up a field just because it was in the wrong order--and many
   * APIs assume this. Therefore, you must be explicit if you want to treat objects as out of order.
   *
   * Use find_field() if you are sure fields will be in order (or are willing to treat it as if the
   * field wasn't there when they aren't).
   *
   * You must consume the fields on an object one at a time. A request for a new key
   * invalidates previous field values: it makes them unsafe. E.g., the array
   * given by content["bids"].get_array() should not be accessed after you have called
   * content["asks"].get_array(). You can detect such mistakes by first compiling and running
   * the code in Debug mode (or with the macro `SIMDJSON_DEVELOPMENT_CHECKS` set to 1): an
   * OUT_OF_ORDER_ITERATION error is generated.
   *
   * You are expected to access keys only once. You should access the value corresponding to a key
   * a single time. Doing object["mykey"].to_string() and then again object["mykey"].to_string()
   * is an error.
   *
   * @param key The key to look up.
   * @returns The value of the field, or NO_SUCH_FIELD if the field is not in the object.

//
// ### Live States
//
// While iterating or looking up values, depth >= iter->depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the array is first found and the iterator is just past the `{`.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the `,` before the next value (or `]`). In this state,
//   depth == iter->depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter->depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter->depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the array iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet element may be missing or not be an
//   array--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter->depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between elements,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter->depth == depth, and at_start == false.
//
// ## Terminal State
//
// The terminal state has iter->depth < depth. at_start is always false.
//
// - Finished: When we have reached a `]` or have reported an error, we are finished. We signal this
//   by decrementing depth. In this state, iter->depth < depth, at_start == false, and
//   error == SUCCESS.

       * Whenever we move to another window, we need to update all pointers to make

       *
       * Take this input:
       *
       * {"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]  [15,  11,   12, 13]  [154,  110,   112, 1311]
       *
       * Say you process the following window...
       *
       * '{"z":5}  {"1":1,"2":2,"4":4} [7,  10,   9]'
       *
       * When you do so, the json_iterator has a pointer at the beginning of the memory region
       * (pointing at the beginning of '{"z"...'.
       *
       * When you move to the window that starts at...
       *
       * '[7,  10,   9]  [15,  11,   12, 13] ...
       *
       * then it is not sufficient to just run stage 1. You also need to re-anchor the
       * json_iterator so that it believes we are starting at '[7,  10,   9]...'.
       *
       * Under the DOM front-end, this gets done automatically because the parser owns
       * the pointer the data, and when you call stage1 and then stage2 on the same
       * parser, then stage2 will run on the pointer acquired by stage1.
       *
       * That is, stage1 calls "this->buf = _buf" so the parser remembers the buffer that
       * we used. But json_iterator has no callback when stage1 is called on the parser.
       * In fact, I think that the parser is unaware of json_iterator.
       *
       *
       * So we need to re-anchor the json_iterator after each call to stage 1 so that
       * all of the pointers are in sync.

// ### Live States
//
// While iterating or looking up values, depth >= iter.depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the object is first found and the iterator is just past the {.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the , or } before the next value. In this state,
//   depth == iter.depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
//   object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State
//
// The terminal state has iter.depth < depth. at_start is always false.
//
// - Finished: When we have reached a }, we are finished. We signal this by decrementing depth.
//   In this state, iter.depth < depth, at_start == false, and error == SUCCESS.

   * is that you first peek and check that you have desired type. If you do,
   * and only if you do, then you advance.
   *
   * We used to unconditionally advance. But this made reasoning about our
   * current state difficult.
   * Suppose you always advance. Look at the 'value' matching the key
   * "shadowable" in the following example...
   *
   * ({"globals":{"a":{"shadowable":[}}}})
   *
   * If the user thinks it is a Boolean and asks for it, then we check the '[',
   * decide it is not a Boolean, but still move into the next character ('}'). Now
   * we are left pointing at '}' right after a '['. And we have not yet reported
   * an error, only that we do not have a Boolean.
   *
   * If, instead, you just stand your ground until it is content that you know, then
   * you will only even move beyond the '[' if the user tells you that you have an
   * array. So you will be at the '}' character inside the array and, hopefully, you
   * will then catch the error because an array cannot start with '}', but the code
   * processing Boolean values does not know this.
   *
   * So the contract is: first call 'peek_...' and then call 'advance_...' only
   * if you have determined that it is a type you can handle.
   *
   * Unfortunately, it makes the code more verbose, longer and maybe more error prone.

   *   // Prints 1 2 3
   *
   * No copy of the input buffer is made.
   *
   * The function is lazy: it may be that no more than one JSON document at a time is parsed.
   *
   * The caller is responsabile to ensure that the input string data remains unchanged and is
   * not deleted during the loop.
   *
   * ### Format
   *
   * The buffer must contain a series of one or more JSON documents, concatenated into a single
   * buffer, separated by ASCII whitespace. It effectively parses until it has a fully valid document,
   * then starts parsing the next document at that point. (It does this with more parallelism and
   * lookahead than you might think, though.)
   *
   * documents that consist of an object or array may omit the whitespace between them, concatenating
   * with no separator. Documents that consist of a single primitive (i.e. documents that are not
   * arrays or objects) MUST be separated with ASCII whitespace.
   *
   * The characters inside a JSON document, and between JSON documents, must be valid Unicode (UTF-8).
   *
   * The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
   * Setting batch_size to excessively large or excessively small values may impact negatively the
   * performance.
   *
   * ### REQUIRED: Buffer Padding
   *
   * The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
   * those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
   * using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
   * SIMDJSON_PADDING bytes to avoid runtime warnings.
   *
   * ### Threads
   *
   * When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
   * hood to do some lookahead.
   *
   * ### Parser Capacity
   *
   * If the parser's current capacity is less than batch_size, it will allocate enough capacity
   * to handle it (up to max_capacity).
   *
   * @param buf The concatenated JSON to parse.
   * @param len The length of the concatenated JSON.
   * @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
   *                   spot is cache-related: small enough to fit in cache, yet big enough to
   *                   parse as many documents as possible in one tight loop.
   *                   Defaults to 10MB, which has been a reasonable sweet spot in our tests.
   * @param allow_comma_separated (defaults on false) This allows a mode where the documents are
   *                   separated by commas instead of whitespace. It comes with a performance
   *                   penalty because the entire document is indexed at once (and the document must be
   *                   less than 4 GB), and there is no multithreading. In this mode, the batch_size parameter
   *                   is effectively ignored, as it is set to at least the document size.
   * @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
   *         - MEMALLOC if the parser does not have enough capacity and memory allocation fails
   *         - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
   *         - other json errors if parsing fails. You should not rely on these errors to always the same for the
   *           same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

//
// ### Live States
//
// While iterating or looking up values, depth >= iter->depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the array is first found and the iterator is just past the `{`.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the `,` before the next value (or `]`). In this state,
//   depth == iter->depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter->depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter->depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the array iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet element may be missing or not be an
//   array--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter->depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between elements,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter->depth == depth, and at_start == false.
//
// ## Terminal State
//
// The terminal state has iter->depth < depth. at_start is always false.
//
// - Finished: When we have reached a `]` or have reported an error, we are finished. We signal this
//   by decrementing depth. In this state, iter->depth < depth, at_start == false, and
//   error == SUCCESS.

// ### Live States
//
// While iterating or looking up values, depth >= iter.depth. at_start may vary. Error is
// always SUCCESS:
//
// - Start: This is the state when the object is first found and the iterator is just past the {.
//   In this state, at_start == true.
// - Next: After we hand a scalar value to the user, or an array/object which they then fully
//   iterate over, the iterator is at the , or } before the next value. In this state,
//   depth == iter.depth, at_start == false, and error == SUCCESS.
// - Unfinished Business: When we hand an array/object to the user which they do not fully
//   iterate over, we need to finish that iteration by skipping child values until we reach the
//   Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
//   `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
//   object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
//   iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
//   we flag that as an error and treat it exactly the same as a Chained Error. In this state,
//   error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State
//
// The terminal state has iter.depth < depth. at_start is always false.
//
// - Finished: When we have reached a }, we are finished. We signal this by decrementing depth.
//   In this state, iter.depth < depth, at_start == false, and error == SUCCESS.
