rustlings 🦀❤️

Greetings and welcome to rustlings. This project contains solutions to small exercises to get you used to reading and writing Rust code. This includes reading and responding to compiler messages!

• The Book - The most comprehensive resource for learning Rust, but a bit theoretical sometimes. You will be using this along with Rustlings!
• Rust By Example - Learn Rust by solving little exercises! It's almost like rustlings, but online

Run rustlings to get started.

Doing exercises

The exercises are sorted by topic and can be found in the subdirectory rustlings/exercises/<topic>. For every topic there is an additional README file with some resources to get you started on the topic. We really recommend that you have a look at them before you start.

The task is simple. Most exercises contain an error that keep it from compiling, and it's up to you to fix it! Some exercises are also run as tests, but rustlings handles them all the same. To run the exercises in the recommended order, execute:

rustlings watch

This will try to verify the completion of every exercise in a predetermined order (what we think is best for newcomers). It will also rerun automatically every time you change a file in the exercises/ directory. If you want to only run it once, you can use:

rustlings verify

This will do the same as watch, but it'll quit after running.

In case you want to go by your own order, or want to only verify a single exercise, you can run:

rustlings run myExercise1

In case you get stuck, you can run the following command to get a hint for your exercise:

rustlings hint myExercise1

Testing yourself

After every couple of sections, there will be a quiz that'll test your knowledge on a bunch of sections at once. These quizzes are found in exercises/quizN.rs.
