<h2>Tokio v1.45.1</h2>
<h1>1.45.1 (May 24th, 2025)</h1>
<p>This fixes a regression on the wasm32-unknown-unknown target, where
code that previously did not panic due to calls to
<code>Instant::now()</code> started failing. This is due to the
stabilization of the first time-based metric.</p>

<ul>
<li>Disable time-based metrics on wasm32-unknown-unknown (<a

Updates `tempfile` from 3.19.1 to 3.20.0
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/Stebalien/tempfile/blob/master/CHANGELOG.md">tempfile's
changelog</a>.</em></p>
<blockquote>
<h2>3.20.0</h2>
<p>This release mostly unifies the behavior/capabilities around
"keeping" temporary files:</p>
<ul>
<li>Rename <code>Builder::keep(bool)</code> (via deprecation) to
<code>Builder::disable_cleanup(bool)</code> to make it clear that
behaves differently from <code>NamedTempFile::keep()</code>. The former
disables automatic cleanup while the latter <em>consumes</em> the
<code>NamedTempFile</code> object entirely and unsets the
"temporary file" attribute (on Windows).</li>
<li>Rename <code>TempDir::into_path</code> (via deprecation) to
<code>TempDir::keep</code> to mirror
<code>NamedTempFile::keep</code>.</li>
<li>Add <code>TempDir::disable_cleanup</code>,
<code>NamedTempFile::disable_cleanup</code>, and
<code>TempPath::disable_cleanup</code> making it possible to disable
automatic cleanup in-place <em>after</em> creating a temporary
file/directory (equivalent to calling
<code>Builder::disable_cleanup</code> before creating the
file/directory).</li>
</ul>
<p>Additionally, it adds a few spooled temporary file features:</p>
<ul>
<li>Add <code>SpooledTempFile::into_file</code> for turning a
<code>SpooledTempFile</code> into a regular unnamed temporary file,
writing it to the backing storage ("rolling" it) if it was
still stored in-memory.</li>
<li>Add <code>spooled_tempfile_in</code> and
<code>SpooledTempFile::new_in</code> methods for creating spooled
temporary files in a specific directory. This makes it possible to
choose the backing device for your spooled temporary file which is
rather important on Linux where the default temporary directory is
likely backed by memory (defeating the entire point of having a spooled
temporary file).</li>
</ul>
<p>Finally, this release improves documentation, especially the
top-level documentation explaining which temporary file type to use.</p>
<p><strong>BREAKING</strong> for those with
<code>deny(warnings)</code>:</p>
<ul>
<li><code>Builder::keep</code> deprecated in favor of
<code>Builder::disable_cleanup</code>.</li>
<li><code>TempDir::into_path</code> is deprecated in favor of
<code>TempDir::keep</code>.</li>
</ul>
<p><strong>BREAKING</strong>:</p>

`println!` adds references (&) to its arguments, to avoid moving them.
This is undesirable here, because it is extremely error-prone to take
references to `static mut`s. We could `println!("{}", {counter})`, but
this is somewhat exotic syntax and just sticking with `dbg!` also avoids
this problem as it does not add references.
The content slides all use `fn main`, with the exception of the testing
segment. But with this change, where it makes sense exercises use tests
instead, and not both tests and `fn main`.
A small change in `book.js` supports running tests when a code sample
does not have `fn main` but does have `#[test]`, so these work
naturally.
Fixes#1581.
The old slice was doing several things at the same time: demonstrating
both external functions as well as unsafe Rust functions.
We now treat those two topics separately. In addition, the “Calling
Unsafe Functions” heading has become its own slide with a non-crashing
example that shows what can go wrong if an argument is misunderstood
in a call to an unsafe function. The old example didn’t actually
illustrate the danger clearly: it would produce mangled UTF-8 output,
which the Playground server refuses to print.
Part of #2445.

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.
I've taken some work by @fw-immunant and others on the new organization
of the course and condensed it into a form amenable to a text editor and
some computational analysis. You can see the inputs in `course.py` but
the interesting bits are the output: `outline.md` and `slides.md`.
The idea is to break the course into more, smaller segments with
exercises at the ends and breaks in between. So `outline.md` lists the
segments, their duration, and sums those durations up per-day. It shows
we're about an hour too long right now! There are more details of the
segments in `slides.md`, or you can see mostly the same stuff in
`course.py`.
This now contains all of the content from the v1 course, ensuring both
that we've covered everything and that we'll have somewhere to redirect
every page.
Fixes#1082.
Fixes#1465.
