Playground

Write any Rust program and run it here, compiled by the real Rust compiler (stable, edition 2024) on the Rust Playground.

• Give your program input and command-line arguments, and see its output, panics and compiler errors explained in plain English.
• Popular crates are available: serde, serde_json, tokio, anyhow, thiserror, regex, itertools, rayon and chrono.
• Your code is saved in your browser, and Share makes a link that carries it.
