Learn Rust

Why learn Rust?

Rust is the most loved programming language seven years running. It combines the performance of C++ with memory safety guarantees — no garbage collector, no null pointer exceptions, no data races. Companies like Mozilla, Cloudflare, Discord, and AWS use Rust for systems programming, web infrastructure, and game engines.

What you'll learn in this Rust tutorial

This free, interactive Rust course covers variables, data types, ownership, borrowing, lifetimes, structs, enums, pattern matching, traits, error handling, generics, concurrency, and modules — all by compiling and running real Rust code in your browser.
