Since https://github.com/rust-lang/rust/pull/88679, rustdoc doesn't load crates eagerly.
Add an explicit `extern crate` item to make sure the crate is loaded and the bug reproduces.
You can verify this fix by adding `// compile-flags: -Znormalizing-docs` and running the test.
In particular, this allows rustdoc to recover from cycle errors when normalizing associated types for documentation.
In the past, `@jackh726` has said we need to be careful about overflow errors:
> Off the top of my head, we definitely should be careful about treating overflow errors the same as
"not implemented for some reason" errors. Otherwise, you could end up with behavior that is
different depending on recursion depth. But, that might be context-dependent.
But cycle errors should be safe to unconditionally report; they don't depend on the recursion depth, they will always be an error whenever they're encountered.
For this rule to have an actual effect, the border-bottom width needs
specified, elsewhere, without also specifying the color. This doesn't
happen. Ever since 88b137d5fe, every spot
where headers get a border assigned to them also assigns the color.

`@rustbot` modify labels: rollup
This class was originally added in 73b97c7e7c
to support hiding and showing the item, because `main.js` went through all
`docblock` elements in the DOM and added toggles to them.
73b97c7e7c/src/librustdoc/html/static/main.js (L1856-L1867)
The `item-decl` is no longer auto-hidden since
c96f86de30 removed it.
`item-decl` used to be called `type-decl`: that name was changed in
8b7a2dd462.
The `docblock` class is no longer used for implementing toggles, since
rustdoc switched to using `<details>` elements.
Avoid duplicating StorageLive in let-else
cc `@est31`
Fix#101867Fix#101932#101410 introduced directives to activate storages of bindings in let-else earlier. However, since it is using the machinery of `match` and friends for pattern matching and binding, those storages are activated for the second time. This PR adjusts this behavior and avoid the duplicated activation for let-else statements.
Add all submodules to the list of directories tidy skips
Tidy contains a blacklist of directories that it is not visiting. This list is also used by the `replace-version-placeholder` tool added by #100591 , to determine the directories to do its replacement from. Generally, tidy does not check submodules, but this is not done consistently for all submodules. This PR adds the submodules that were previously missing, so that the `replace-version-placeholder` tool does not attempt to change content of the books. This was needed because `rustc-dev-guide` contains the placeholder, leading to #102014.
Fixes#102014
interpret: expose generate_stacktrace without full InterpCx
In Miri we sometimes want to emit diagnostics without having a full `&InterpCx` available. To avoid duplicating code, this adds a way to get a stacktrace from an arbitrary slice of interpreter frames, that Miri can use with access to just a thread manager.
Update release notes for 1.64
This PR makes a few updates to the release notes to bring them on-par with the release notes of other releases:
* The wording on some items has been changed to be more consistent and better describe what each change means, rather than using the PR title.
* Items that were also in the compatibility notes have been removed from the other sections, only keeping them in the compat notes.
* Diagnostics and ICE fixes have been removed from the notes.
* The cargo section has been made more consistent.

Add unit test for identifier Unicode emoji diagnostics
Seems current diagnostics has some support for emoji usages, however it seems outdated and incomplete. This adds a simple unit test to showcase the status quo.
Add help for invalid inline argument
Fixes#101712
Removed 1 part of the test as its identical with another one. Do let me know if this is undesirable, so I can revert those changes.
Make `from_waker`, `waker` and `from_raw` unstably `const`
Make
- `Context::from_waker`
- `Context::waker`
- `Waker::from_raw`
`const`.
Also added a small test.
Tone down explanation on RefCell::get_mut
The language around `RefCell::get_mut` is remarkably sketchy and especially to the novice seems to quite strongly discourage using the method ("be cautious", "Also, please be aware", "special circumstances", "usually not what you want"). It was added six years ago in #40634 due to confusion about when to use `get_mut` and `borrow_mut`.
While its signature limits the use-cases for `get_mut`, there is no chance for a safety footgun, and readers can be made aware of `borrow_mut` more softly. I've also just sent a [PR](https://github.com/rust-lang/rust-clippy/issues/9044) to lint situations where `get_mut` could be used to improve ergonomics and performance.
So this PR tones down the language around `get_mut` and also brings it more in line with [`std::sync::Mutex::get_mut()`](https://doc.rust-lang.org/stable/std/sync/struct.Mutex.html#method.get_mut).
note on deterministic 'fake' API implementations
Now that we also have fake clocks, it seems prudent to warn about this at the top of the readme.

[arithmetic-side-effects] Finish non-overflowing ops
Extends https://github.com/rust-lang/rust-clippy/pull/9474 to also take into consideration "raw" binary operations. For example, `let a = b / 2` and `let a = 1 * b` won't trigger the lint.

`EarlyBinder` prevent misuse
folding a type before substituting is pretty much always wrong and could happen by accident, e.g. see https://github.com/rust-lang/rust/pull/99798#discussion_r968666538
this PR removes the `TypeFoldable` and `TypeVisitable` impl from `EarlyBinder`.
