[rustdoc] Only keep impl blocks from bodies
Fixes https://github.com/rust-lang/rust/issues/111415.
The problem was that we kept everything inside bodies whereas only impl blocks are actually accessible from outside bodies.
r? `@notriddle`
fix(diagnostic): wrap parens for ref impl trait param
Fixes https://github.com/rust-lang/rust/issues/99597
When parameters are an `impl_trait` which it needed to add trait, and it is a reference, add parentheses to the type of the parameter in the suggestion
Change Vec examples to not assert exact capacity except where it is guaranteed
It was [brought up on discord](https://discord.com/channels/273534239310479360/818964227783262209/1107633959329878077) that the `Vec::into_boxed_slice` example contradicted the `Vec::with_capacity` docs in that the returned `Vec` might have _more_ capacity than requested.
So, to reduce confusion change all the `assert_eq!(vec.capacity(), _)` to `assert!(vec.capacity() >= _)`, except in 4 examples that have guaranteed capacities: `Vec::from_raw_parts`, `Vec::from_raw_parts_in`, `Vec::<()>::with_capacity`,`Vec::<(), _>::with_capacity_in`.
Erase `ReError` properly
Fixes#111341
Since we check whether a type has free regions before erasing (to short circuit unnecesary folding), we need to consider `ReError` as a free region, or else we'll skip it when erasing a type that only mentions `ReError`.

Handle error body in generator layout
Fixes#111468
I feel like making this query return `Option<GeneratorLayout>` might be better but had some issues with that approach
Use error term in projection if missing associated item in new solver
We were previously delaying a bug but not bailing, leading to an ICE in the `tcx.type_of(assoc_def.item.def_id)` call below.
Hide repr attribute from doc of types without guaranteed repr
Rustdoc has an undesirable behavior of blindly copying `repr` into the documentation of structs and enums, even when there is no particular repr that the type guarantees to its users. This is a source of confusion for standard library users who assume the fact that a repr is documented means it must be something the standard library promises they can rely on (in transmutes, or FFI).
Some issues on the topic of rustdoc's incorrect handling of `repr`:
- https://github.com/rust-lang/rust/issues/66401
- https://github.com/rust-lang/rust/issues/90435
In places, the standard library currently works around this confusing rustdoc behavior by just omitting `repr(transparent)` altogether even where it should be required if equivalent code were being written outside of the standard library. See #61969.
IMO that is even more confusing, even for standard library maintainers — see https://github.com/rust-lang/rust/pull/105018#discussion_r1058400997. It's also not something that works for other reprs like `C` or `u8` which cannot just be omitted even in standard library code.
This PR tries a different approach for some types that are being currently incorrectly documented with a repr.
> **Warning**
> This PR does not imply that every type that still has a `repr` attribute in its docs after this PR is now public for users to rely on. This PR only tries to reduce harm from this longstanding rustdoc issue.
The recent LLVM 16 update changes code-gen to be not branchless anymore, in the
slice::sort implementation merge function. This improves performance by 30% for
random patterns, restoring the performance to the state with LLVM 15.
Always fall back to PartialEq when a constant in a pattern is not recursively structural-eq
Right now we destructure the constant as far as we can, but with this PR we just don't take it apart anymore. This is preparatory work for moving to always using valtrees, as these will just do a single conversion of the constant to a valtree at the start, and if that fails, fall back to `PartialEq`.
This removes a few cases where we emitted the `unreachable pattern` lint, because we stop looking into the constant deeply enough to detect that a constant is already covered by another pattern.
Previous work: https://github.com/rust-lang/rust/pull/70743
This is groundwork towards fixing https://github.com/rust-lang/rust/issues/83085 and https://github.com/rust-lang/rust/issues/105047

Fix release date of 1.58.1 in release notes.
This fixes the release notes to have the correct release date for 1.58.1. The [blog announcement](https://blog.rust-lang.org/2022/01/20/Rust-1.58.1.html) has the correct date and link (which is otherwise broken without this change).
Closes#94278
Add clubby789 to the bootstrap review rotation
r? `````@clubby789````` - thank you for volunteering!
I have been meaning for a very long time now to write up how to do reviews, but I haven't gotten around to it yet :( here is a short summary:
1. If you're not sure what the changes does or if it's ok, always feel free to ping someone else on the team, especially in the first few weeks. You can use `r? bootstrap` to get triagebot to assign someone else.
2. Bootstrap unfortunately has very few tests. Things that touch CLI or toml parsing should likely have a test in `src/bootstrap/config/tests.rs`; things that touch "core" build logic should have a test in `builder/tests.rs`, anything else kinda just slips in :( see https://github.com/rust-lang/rust/issues/102563 for ideas on how to improve the situation here.
3. "Major" changes should be documented in `src/bootstrap/CHANGELOG.md`. "Major" is up to you, but if it breaks a config option or otherwise is likely to break *someone's* build, it's probably major. If it breaks nearly *everyone*'s build, it should also update `VERSION` in `lib.rs`; this should be very rare. Please also ping me or Mark-Simulacrum for major changes (I might set up a triagebot ping for this so you don't have to remember).
4. Once you've approved the PR, tell bors it's ok - you've been contributing for a while so you know how bors works, but here's a cheatsheet just in case: https://bors.rust-lang.org
Documentation about how to use bootstrap lives at https://rustc-dev-guide.rust-lang.org/building/bootstrapping.html; internal docs live in `src/bootstrap/README.md`. The latter unfortunately is not very complete.
Suppress "erroneous constant used" for constants tainted by errors
When constant evaluation fails because its MIR is tainted by errors,
suppress note indicating that erroneous constant was used, since those
errors have to be fixed regardless of the constant being used or not.
Fixes#110891.
Document that `missing_copy_implementations` and `missing_debug_implementations` only apply to public items.
I encountered #111359 (fixed) and noticed that the documentation didn't say that it was _intended_ that `missing_debug_implementations` only applies to public items. This PR fixes that, and makes the same wording change to `missing_copy_implementations` which has the same condition.
I chose the words to also be similar to `missing_docs` which already had such a remark.
Recover `impl<T ?Sized>` correctly
Fixes#111327
r? ````@Nilstrieb```` but you can re-roll
Alternatively, happy to close this if we're okay with just saying "sorry #111327 is just a poor side-effect of parser ambiguity" 🤷
