2023-04-29Rollup merge of #110958 - compiler-errors:stdlib-refinement, r=cuviperDylan DPC-17/+65
Make sure that some stdlib method signatures aren't accidental refinements In the process of implementing https://rust-lang.github.io/rfcs/3245-refined-impls.html, I found a bunch of stdlib implementations that accidentally "refined" their method signatures by dropping (unnecessary) bounds. This isn't currently a problem, but may become one if/when method signature refining is stabilized in the future. Shouldn't hurt to make these signatures a bit more accurate anyways. NOTE (just to be clear lol): This does not affect behavior at all, since we don't actually take advantage of refined implementations yet!

Updating Wake example to use new 'pin!' macro Closes: https://github.com/rust-lang/rust/issues/109965 I have already had this reviewed and approved here: https://github.com/rust-lang/rust/pull/110026 . But because I had some git issues and chose the "nuke it" option as my solution it didn't get merged. I nuked it too quickly. I am sorry for trouble of reviewing twice.

2023-04-22Auto merge of #109507 - Amanieu:panic-oom-payload, r=davidtwcobors-17/+78
Report allocation errors as panics OOM is now reported as a panic but with a custom payload type (`AllocErrorPanicPayload`) which holds the layout that was passed to `handle_alloc_error`. This should be review one commit at a time: - The first commit adds `AllocErrorPanicPayload` and changes allocation errors to always be reported as panics. - The second commit removes `#[alloc_error_handler]` and the `alloc_error_hook` API.

Improve documentation for str::replace() and str::replacen() Currently, to know what the function will return when the pattern doesn't match, the docs require the reader to understand the implementation detail and mentally evaluate or run the example code. It is not immediately clear. This PR makes it more explicit so the reader can quickly find the information.
2023-03-30Rollup merge of #106985 - jofas:106746-fix, r=ChrisDentonYuki Okushi-10/+10
Enhanced doucmentation of binary search methods for `slice` and `VecDeque` for unsorted instances Fixes #106746. Issue #106746 raises the concern that the binary search methods for slices and deques aren't explicit enough about the fact that they are only applicable to sorted slices/deques. I changed the explanation for these methods. I took the relatively harsh description of the behaviour of binary search on unsorted collections ("unspecified and meaningless") from the description of the [`partition_point`](https://doc.rust-lang.org/std/primitive.slice.html#method.partition_point) method: > If this slice is not partitioned, the returned result is unspecified and meaningless, as this method performs a kind of binary search.

2023-03-29Rollup merge of #109693 - workingjubilee:maybe-unconstify-alloc, r=fee1-deadMatthias Krüger-38/+19
Remove ~const from alloc There is currently an effort underway to stop using `~const Trait`, temporarily, so as to refactor the logic underlying const traits with relative ease. This means it has to go from the standard library, as well. I have taken the initial step of just removing these impls from alloc, as removing them from core is a much more tangled task. In addition, all of these implementations are one more-or-less logically-connected group, so reverting their deconstification as a group seems like it will also be sensible. r? `@fee1-dead`
