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 when teaching Rust to experienced software engineers. They typically have 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 will be less useful for self-study since you miss out on the discussions happening in the classroom. You don't see the questions and answers and you don't see the compiler errors we trigger when going through the code samples. We hope to improve on this via speaker notes and by publishing videos.

Setup

The course is built using a few tools:

• mdbook
• mdbook-svgbob
• mdbook-i18n-helpers and i18n-report
• mdbook-exerciser
• mdbook-course
• mdbook-linkcheck2

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 install these tools with:

cargo xtask install-tools

Note We use xtask for task automation within the project (e.g. installing required tools). Xtask is not a package that you should install. Visit https://github.com/matklad/cargo-xtask for more information.

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.
