%description
Rust is a fast systems programming language that guarantees memory safety and
offers painless concurrency (no data races). It does not employ a garbage
collector and has minimal runtime overhead.

This package contains the compiler (rustc), as well as standard libraries, tools
and documentation for Rust.
