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.
The licenses end up in the PO files, causing extra unnecessary for work
our translators. We save about 300 lines from each PO file with this.
This also solves another small problem: when a file is included with an
anchor, other anchors are automatically stripped away. This removes some
confusing `// ANCHOR: foo` and `// ANCHOR_END: foo` lines in the
solutions.
Hello there 👋 I'm the author of the `tokio-websockets` crate and
today we published version `0.4.0` of the crate, which finally makes the
public API consistent and aligns it with expectations.
`WebsocketStream` now implements the `Stream` trait, so calling `next()`
has to be done via `StreamExt` now. `connect()` returns a tuple of
`(WebsocketStream, Response)`, so that has to be deconstructed now. And
finally, `as_text()` now returns an `Option<&str>` instead of
`Result<&str, Error>`.
And, *very* importantly: The old `WebsocketStream::next` was **not**
cancellation safe, the new `Stream` implementation is. The exercise uses
`select!`, which very well might have caused misbehavior.
Since we also emptied the default features, I've added the very minimal
ones required to compile the exercise.
This is my first contribution here, so feel free to point me to some
things if I'm missing anything. I wasn't really sure what to do about
the translations, I guess I should leave them as is and they'll be
updated by translators in other PRs?
