Comprehensive Rust 🦀

This repository has the source code for Comprehensive Rust 🦀, a multi-day Rust course developed by the Android team. The course covers all aspects of Rust, from basic syntax to generics and error handling. It also includes deep dives on Android, Chromium, bare-metal, and concurrency.

Read the course at https://google.github.io/comprehensive-rust/.

Course Format and Target Audience

The course is used internally at Google to teach Rust to experienced software engineers, typically with a background in C++ or Java.

The course is taught in a classroom setting, and we hope it will be useful for others who want to teach Rust to their team. The course is less ideal for self-study, since you would miss out on classroom discussions. You would not see the questions and answers, nor the compiler errors we trigger when going through the code samples. We hope to improve the self-study experience via speaker notes and by publishing videos.

Setup

The course is built using a few tools:

First, install Rust by following the instructions on https://rustup.rs/. Then clone this repository:

git clone https://github.com/google/comprehensive-rust/
cd comprehensive-rust

Then run the following command to install the correct versions of all tools mentioned above:

cargo xtask install-tools

This uses cargo install to install the tools, so you will find them in your ~/.cargo/bin/ directory afterwards.

Commands

Here are some of the commonly used commands you can run in the project. Run cargo xtask to view all available commands.

Command	Description
`cargo xtask install-tools`	Install all the tools the project depends on.
`cargo xtask serve`	Start a web server with the course. You’ll find the content on http://localhost:3000. To serve any of the translated versions of the course, add the language flag (–language or -l) followed by xx, where xx is the ISO 639 language code (e.g. cargo xtask serve -l da for the Danish translation).
`cargo xtask rust-tests`	Test the included Rust snippets.
`cargo xtask web-tests`	Run the web driver tests in the tests directory.
`cargo xtask build`	Create a static version of the course in the `book/` directory. Note that you have to separately build and zip exercises and add them to book/html. To build any of the translated versions of the course, add the language flag (–language or -l) followed by xx, where xx is the ISO 639 language code (e.g. cargo xtask build -l da for the Danish translation). TRANSLATIONS.md contains further instructions.

Note On Windows, you need to enable symlinks (git config --global core.symlinks true) and Developer Mode.
