Rust is a modern systems programming language focusing on safety and speed. It accomplishes these goals by being memory safe without using garbage collection.
Rust by Example is a collection of examples that illustrate various Rust concepts and the standard libraries. You can also check out the source code for this site.
Note: Rust by Example follows the nightly builds until the beta or possibly the 1.0.0 final release. If you're following along on your computer, make sure to have the latest Rust installed.
