A language empowering everyone to build reliable and efficient software.

Rust combines performance with memory safety and a thriving open-source community — from command-line tools and web services to embedded devices.

Get Started Install

Version 1.98.1

main.rs

fn main() {
    // Fearless concurrency, zero-cost abstractions
    let greeting = "Hello, Rust!";
    println!("{greeting}");

    let numbers = [1, 2, 3];
    let sum: i32 = numbers.iter().sum();
    println!("sum = {sum}");
}

Install Rust in one line

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

This installs rustup, the official Rust toolchain installer, and keeps rustc and cargo up to date. Read the full install guide for platform-specific notes.

Performance

Rust is blazingly fast and memory-efficient, with no runtime or garbage collector. It powers performance-critical services and runs comfortably on embedded devices.

Reliability

Rust's rich type system and ownership model guarantee memory-safety and thread-safety, eliminating whole classes of bugs at compile time. Errors are caught before your users see them.

Productivity

Cargo, rustfmt, Clippy, and rustdoc ship with the language. Great documentation, a friendly compiler, and a helpful error format keep you moving fast.

Command Line

Whip up a CLI tool quickly with a dependency-free, easy-to-distribute binary. Cargo makes shipping and cross-compiling painless, so your users just download and run.

WebAssembly

Compile Rust to WebAssembly for fast, small, portable modules that run on the web and at the edge. Tight control over memory makes it ideal for performance-critical front-end code.

Networking

Rust gives you the low-level control needed for modern network services without sacrificing safety. Blazing-fast, predictable binaries make it a natural fit for servers and proxies.

Embedded

Target microcontrollers and bare-metal devices with a no_std-friendly ecosystem. Rust's guarantees help you write dependable firmware with fewer runtime surprises.
