This is the result of running `dprint fmt` after removing `src/` from
the list of excluded directories.
This also reformats the Rust code: we might want to tweak this a bit in
the future since some of the changes removes the hand-formatting. Of
course, this formatting can be seen as a mis-feature, so maybe this is
good overall.
Thanks to mdbook-i18n-helpers 0.2, the POT file is nearly unchanged
after this, meaning that all existing translations remain valid! A few
messages were changed because of stray whitespace characters:
msgid ""
"Slices always borrow from another object. In this example, `a` has to remain "
-"'alive' (in scope) for at least as long as our slice. "
+"'alive' (in scope) for at least as long as our slice."
msgstr ""
The formatting is enforced in CI and we will have to see how annoying
this is in practice for the many contributors. If it becomes annoying,
we should look into fixing dprint/check#11 so that `dprint` can annotate
the lines that need fixing directly, then I think we can consider more
strict formatting checks.
I added more customization to `rustfmt.toml`. This is to better emulate
the dense style used in the course:
- `max_width = 85` allows lines to take up the full width available in
our code blocks (when taking margins and the line numbers into account).
- `wrap_comments = true` ensures that we don't show very long comments
in the code examples. I edited some comments to shorten them and avoid
unnecessary line breaks — please trim other unnecessarily long comments
when you see them! Remember we're writing code for slides 😄
- `use_small_heuristics = "Max"` allows for things like struct literals
and if-statements to take up the full line width configured above.
The formatting settings apply to all our Rust code right now — I think
we could improve this with https://github.com/dprint/dprint/issues/711
which lets us add per-directory `dprint` configuration files. However,
the `inherit: true` setting is not yet implemented (as far as I can
tell), so a nested configuration file will have to copy most or all of
the top-level file.
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.
Press
Articles and blog posts from around the web which cover Comprehensive Rust:
- 2023-09-08: Teaching Rust in 5 days. Comprehensive Rust was used as a base for a 5-day university class on Rust.
- 2023-09-21: Scaling Rust Adoption Through Training. We published a blog post with details on the development of the course.
- 2023-10-02: In Search of Rust Developers, Companies Turn to In-House Training. About how Microsoft, Google, and others are training people in Rust.
Building
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 install these tools with:
cargo install mdbook
cargo install mdbook-svgbob
cargo install mdbook-i18n-helpers
cargo install --path mdbook-exerciser
cargo install --path mdbook-course
Run
mdbook test
to test all included Rust snippets. Run
mdbook serve
to start a web server with the course. You'll find the content on
http://localhost:3000. You can use mdbook build to 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, run MDBOOK_BOOK__LANGUAGE=xx mdbook build -d book/xx
where xx is the ISO 639 language code (e.g. 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.
