Rust overview

Rust is a statically-typed, compiled systems programming language that guarantees memory safety and thread safety at compile time through its ownership and borrow checker system — without a garbage collector. Rust excels in performance-critical contexts: operating system kernels, WebAssembly modules, game engines, network services, and CLI tooling. The async ecosystem (tokio, async-std) enables high-throughput I/O. Cargo is the build system and package manager; crates.io hosts the package registry. Rust is increasingly used in Linux kernel modules, Windows internals, and as a safe replacement for C/C++ in security- sensitive code. The borrow checker makes data races a compile-time error.
