Official Rust WebAssembly Documentation

Memory Safety

Rust's unique ownership system prevents memory bugs at compile time, ensuring safe WebAssembly execution.

Native Performance

Write Rust code that compiles to highly optimized WebAssembly with near-native speed.

Tooling Ecosystem

Comprehensive tooling for seamless WebAssembly development with Rust toolchains.

Start Building

Build WebAssembly modules with Rust in just three steps.

1. Setup

Install rustup components:

rustup target add wasm32-unknown-unknown
cargo install wasm-pack

2. Write Code

Sample Rust function for WebAssembly:

#[wasm_bindgen]
pub fn add(a: i32, b: i32) -> i32 {
a + b
}

3. Deploy

Build and pack your module:

wasm-pack build --target web
npm install ../path/to/your/module
