Rust playground FAQ

Can I run Rust code online here?
Yes. The playground compiles and runs Rust programs in the browser, then shows stdout, stderr, and compiler errors.
Is this playground good for learning ownership?
Yes. Ownership and borrowing examples are a perfect fit because you can quickly edit code and read the compiler's feedback.
Should I use the playground or the lessons first?
Use the playground for quick experiments, then follow the lessons when you want a clear path from fundamentals to real Rust projects.

Your code runs in a secure, isolated sandbox powered by OmniRun — no containers, just hardware-isolated microVMs.
