About Rust

Rust is a systems programming language developed by Mozilla that focuses on performance, memory safety, and concurrency. It guarantees memory safety without a garbage collector and is widely used for system-level programming, web assembly, and command-line tools. Rust's compiler enforces strict compile-time checks, making code safer and more predictable.
