Long overdue.
It felt a bit "odd" self-assigning merit, especially because I think I
haven't nearly contributed enough translations. So I looked at the
[history of `it.po` file](https://github.com/google/comprehensive-rust/commits/main/po/it.po)
and identified also @henrythebuilder as the other "owner" of the Italian
translation (definitely, based on number of lines contributed).
@henrythebuilder please confirm you are comfortable with this.
IMO it is better to explain to users the common usage / applicability
domain for anyhow and thiserror crates

This should be a bit simpler, and notably
* does not require trait objects, which per #1516 should be moved later
in the course
* does not require a lot of futzing with string formatting
But all that hard work developing the GUI exercise is not for naught: it
remains in the "Modules" segment, where students will get a chance to
read some Rust code and reorganize it a little bit.
Fixes#1617.

Attempt to address #1677.
Expert review is needed. The new text is my best guess based on the
original text and other explanations I could find online.
A few things to note:
* I'm trying to distinguish the future we return and the future we
await. My assumption is that the stack contents goes to the future the
code returns, not the future the code is awaiting.
* Readers could be worried if they need to pin the code they write. I'm
reassuring them that the borrow checks would normally catch bad
references.
* I'm intentionally avoiding the words that something is unsafe (or
would be unsafe). The async Rust is safe.
* I'm trying to be clear that `Pin` is a protective wrapper around a
pointer, not a mechanism that changes the pointer or the pointed object.
* Likewise, I don't want to give an impression that an unpinned pointer
to a future is inherently unsafe or invalid. It just cannot be used to
poll the future.
* I dropped the vague mention of the "issues", as it probably refers to
the issue with replacing a future (as opposed to resetting it in place).
It's already mentioned in the notes further on this page. It affects
pinning on stack only, `Box::pin()` can be replaced.

This adds a GH action to add a comment to every PR giving the updated
course schedule with the PR merged.
To accomplish this, I broke `mdbook-course` into a library and two
binaries, allowing the mdbook content to be loaded dynamically outside
of an `mdbook build` invocation.
I think this is a net benefit, but possible improvements include:
* diffing the "before" and "after" schedules and only making the comment
when those are not the same (or replacing the comment with "no schedule
changes")
* including per-segment timing behind `<details>` (with a few minutes
effort I couldn't get this to play nicely with the markdown lists)

Before we would run `mdbook test` using the current Markdown sources.
This is subtly wrong: we publish the course using back-dated sources,
so we should therefore also run the tests using the same sources (this
ensures that the code snippets actually work).
After this commit, all translatable content lives in exactly two
directories:
- `src/`
- `third_party/`
We need to restore both directories when testing and when publishing.
This ensures consistency in the Markdown text and in the included
source code.
A new `.github/workflows/build.sh` script takes care of preparing the
two directories according to the date in the PO file (if any).
To ensure we can restore all of `third_party/` to an old commit, the
non-changing `third_party/mdbook/book.js` file has been moved to
`theme/book.js`. The file is generated by `mdbook init --theme`,
making it suitable for modification by the user (us). Symlinks have
been added to `third_party/mdbook/` to indicate that the files
ultimately came from upstream.
The use of conditionals for error handling makes the code look mode
complex than is.
Read the actual port number from the listener instead of hardcoding port
6142 in two places. That also demonstrates how to deal with ephemeral
ports.

in #1565.
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.

It's clear from the above text and example that the error type returned
by the outer function (`Err` in this case) must implement the `From`
trait to accept the error returned by the inner function (`OtherErr` in
this case).
Currently, `BinaryTree::has` takes its argument by value. This is a
pretty unrealistic API for a Rust library. Let's fix this and take the
argument by reference instead.
