Rustlings 🦀❤️

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

It is recommended to do the Rustlings exercises in parallel to reading the official Rust book, the most comprehensive resource for learning Rust 📚️

Rust By Example is another recommended resource that you might find helpful. It contains code examples and exercises similar to Rustlings, but online.

Getting Started

Installing Rust

Before installing Rustlings, you need to have Rust installed. Visit www.rust-lang.org/tools/install for further instructions on installing Rust. This'll also install Cargo, Rust's package/project manager.

🐧 If you're on Linux, make sure you've installed gcc (for a linker).

Deb: sudo apt install gcc. Dnf: sudo dnf install gcc.

🍎 If you're on MacOS, make sure you've installed Xcode and its developer tools by running xcode-select --install.

Installing Rustlings

The following command will download and compile Rustlings:

cargo install rustlings@6.0.0-beta.9
If the installation fails… (click to expand)
  • Make sure you have the latest Rust version by running rustup update
  • Try adding the --locked flag: cargo install rustlings@6.0.0-beta.9 --locked
  • Otherwise, please report the issue

Initialization

After installing Rustlings, run the following command to initialize the rustlings/ directory:

rustlings init

Now, go into the newly initialized directory and launch Rustlings for further instructions on getting started with the exercises:

cd rustlings/
rustlings

Working environment

Editor

Our general recommendation is VS Code with the rust-analyzer plugin. But any editor that supports rust-analyzer should be enough for working on the exercises.

Terminal

While working with Rustlings, please use a modern terminal for the best user experience. The default terminal on Linux and Mac should be sufficient. On Windows, we recommend the Windows Terminal.

If you use VS Code, the builtin terminal should also be fine.

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 ✅

Watch Mode

After 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.

If detecting file changes in the exercises/ directory fails… (click to expand)

You can add the --manual-run flag (rustlings --manual-run) to manually rerun the current exercise by entering r in the watch mode.

Please report the issue with some information about your operating system and whether you run Rustlings in a container or virtual machine (e.g. WSL).

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 an exercise (you need to reload/reopen its file in your editor afterwards)

See the footer of the list for all possible keys.

Continuing On

Once you've completed Rustlings, put your new knowledge to good use! Continue practicing your Rust skills by building your own projects, contributing to Rustlings, or finding other open-source projects to contribute to.

Uninstalling Rustlings

If you want to remove Rustlings from your system, run the following command:

cargo uninstall rustlings
