What is it?

Rustlings is a set of small, guided exercises for learning Rust. Each exercise is a short file with a compile error, a failing test, or a logic bug that you fix by editing the code. Working through them builds familiarity with Rust syntax, the compiler's error messages, and core language concepts.

The project is designed to be used alongside the official Rust book rather than as a replacement for it. The exercises are run from a command line tool, which checks your progress and moves you to the next one once the current exercise compiles and passes.

The project's website covers setup instructions and more details about how the exercises are organized.

Key features

  • 01Exercises cover Rust syntax, compiler errors, and core language concepts.
  • 02A command line tool checks your solutions and advances you through the exercises.
  • 03Each exercise is a small file you edit directly in your own editor.
  • 04Designed to be worked through alongside the official Rust book.

Use cases

  • Learning Rust for the first time while reading the official book.
  • Practicing reading compiler error messages in a low-stakes setting.
  • Warming up on Rust fundamentals before starting a real project.
