Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. It aims to bring modern language design and an advanced type system to systems programming. Rust does not use a garbage collector, using advanced static analysis to provide deterministic drops instead. It accomplishes this via the concept of ownership.
Rust's core and the standard library are intentionally minimal; batteries are not included. Rustaceans are instead encouraged to add libraries, called crates, to the language by sharing them on crates.io.
Rust is most frequently used for applications where speed, performance and stability are essential. The Awesome Rust list collects examples of Rust projects, which include CLI tools, ORMs, operating systems and games. Regardless of what you build in Rust, it will be fast and memory safe!
