Rust Tutorial

This is a practical guide to Rust for people who are new to it. The lessons are short, every example is real code you can run, and I’ve tried to be honest about the parts that usually give beginners trouble.

Try Rust right now

Here’s a full Rust program. Click Try it Yourself to run it and change the message — it opens in the official Rust Playground, so there’s nothing to install.

fn main() {
    println!("Hello, World!");
}

What you’ll learn

Getting StartedInstall Rust and run your first program.

Variables & TypesStore data and learn Rust's basic types.

FunctionsGroup code into reusable pieces.

OwnershipThe idea at the heart of how Rust manages memory.

BorrowingShare and change data without copying it around.

More to comeControl flow, collections, error handling, and traits.

Why Rust?

Rust is used for the same kind of work as C and C++ — operating systems, browsers, game engines, databases, and command-line tools — anywhere speed and control matter. What’s different is that the Rust compiler catches a whole category of memory bugs before your program runs, and it does that without a garbage collector.

The catch is that Rust is stricter than most languages. It will reject code that other compilers happily accept. In return, you get programs that run fast and don’t fall over the way C programs often do.

That’s the reason it shows up in production at Cloudflare, Discord, and Dropbox, and why the Linux kernel now takes drivers written in Rust.

One honest heads-up: the first couple of weeks can be rough. Ownership and borrowing are genuinely new ideas, and arguing with the compiler is a bit of a rite of passage. It clicks sooner than you’d expect, and this guide is written to get you there with as little pain as possible.

How to use this guide

If you’re starting from zero, work through the topics on the left roughly in order. If you already know some Rust, skip to whatever you need. Every code sample has a Try it Yourself button, so you can run it, break it, and see what happens as you read.

One tip worth knowing up front: read the compiler’s error messages. Rust’s are unusually good — they normally tell you what went wrong and how to fix it, so it pays to actually read them instead of skimming past.
