Rust FAQ
Do I need to install Rust to use this?
No. The Rust 1.82 runtime runs in your browser via CodeLab's embedded editor. Open the compiler, pick Rust, and press Run.
Is running Rust online free?
Yes. The CodeLab Playground is free with no account. Optional paid plans add privacy and larger limits — see the pricing page.
How do I handle input in Rust?
Use the stdin panel inside the editor for piped input, then press Run. The sample below reads a name from stdin.
