Rust Playground

Run Rust code using the official Rust Playground — run by the Rust project, with the real rustc compiler, rustfmt, and Clippy available.

fn main() {
    println!("Hello from the Rust Playground!");
}

Paste the snippet above (or your own Rust code) and run it there — real compilation, real output.

Why this links out instead of embedding

Rust compiles to native machine code via LLVM — there's no browser-native way to run that in a tab. The official Rust Playground handles this the right way: your code runs against a real rustc in a disposable container, against the current stable, beta, or nightly toolchain, with the top 100 most-downloaded crates available for use. That's a level of fidelity a browser reimplementation couldn't match.

About the Rust Playground

The Rust Playground is hosted by Integer 32 and endorsed as the project's official playground, linked directly from doc comments via #[doc(html_playground_url = ...)] and from the Rust website itself. Beyond running code, it can show the compiled assembly, LLVM IR, or Rust MIR, run Clippy lints, and format code with rustfmt — and you can save a snippet to a GitHub Gist to share it.
