Rustlings
Fix small broken Rust programs until they compile and pass tests
Rustlings is a set of small exercises that get you used to reading and writing Rust. Most exercises contain an error that stops them from compiling, and your job is to fix it. Others have tests that you must make pass. When one works, you move on to the next.

About Rustlings
The exercises are sorted by topic, and the project suggests using them alongside the official Rust book. It suits people new to Rust, though some programming experience helps.
You install it with Cargo and run it in your terminal. Watch mode reruns the current exercise each time you save, and you can ask for a hint when stuck. It is free and open source under the MIT license, hosted by the rust-lang organization.
