Usage

Doing exercises

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

Most exercises contain an error that keeps them from compiling, and it's up to you to fix it! Some exercises contain tests that need to pass for the exercise to be done ✅

Search for TODO and todo!() to find out what you need to change. Ask for hints by entering h in the watch mode 💡

Watch Mode

After the initialization, Rustlings can be launched by simply running the command rustlings.

This will start the watch mode which walks you through the exercises in a predefined order (what we think is best for newcomers). It will rerun the current exercise automatically every time you change the exercise's file in the exercises/ directory.

Exercise List

In the watch mode (after launching rustlings), you can enter l to open the interactive exercise list.

The list allows you to…

• See the status of all exercises (done or pending)
• c: Continue at another exercise (temporarily skip some exercises or go back to a previous one)
• r: Reset status and file of the selected exercise (you need to reload/reopen its file in your editor afterwards)

See the footer of the list for all possible keys.

Questions?

If you need any help while doing the exercises and the builtin hints aren't helpful, feel free to ask in the Q&A discussions if your question isn't answered there 💡
