2025-02-23	rename sub_ptr 😅	bendn	-1/+1

2024-07-29	Reformat `use` declarations.	Nicholas Nethercote	-1/+1
	The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.
2023-05-07	enable `rust_2018_idioms` for doctests	ozkanonur	-1/+1

2023-04-22	Rollup merge of #110635 - scottmcm:zst-checks, r=the8472	Yuki Okushi	-3/+1
	More `IS_ZST` in `library` I noticed that `post_inc_start` and `pre_dec_end` were doing this check in different ways https://github.com/rust-lang/rust/blob/d19b64fb54391b64ce99981577c67c93ac2a9ffa/library/core/src/slice/iter/macros.rs#L76-L93 so started making this PR, then added a few more I found since I was already making changes anyway.

2023-04-20	More `mem::take` in `library`	Scott McMurray	-1/+1
	A bunch of places were using `replace(…, &mut [])`, but that can just be `take`.
2023-01-17	Don't do pointer arithmetic on pointers to deallocated memory	The 8472	-3/+3
	vec::Splice can invalidate the slice::Iter inside vec::Drain. So we replace them with dangling pointers which, unlike ones to deallocated memory, are allowed.
2022-09-22	Make ZST checks in core/alloc more readable	Scott McMurray	-2/+2
	There's a bunch of these checks because of special handing for ZSTs in various unsafe implementations of stuff. This lets them be `T::IS_ZST` instead of `mem::size_of::<T>() == 0` every time, making them both more readable and more terse. Not proposed for stabilization at this time. Would be `pub(crate)` except `alloc` wants to use it too. (And while it doesn't matter now, if we ever get something like 85836 making it a const can help codegen be simpler.)
2022-08-28	fill-in tracking issue for `feature(drain_keep_rest)`	Maybe Waffle	-1/+1

2022-08-28	add examples to `vec::Drain{,Filter}::keep_rest` docs	Maybe Waffle	-0/+18

2022-06-05	Add vec::Drain{,Filter}::keep_rest	Maybe Waffle	-1/+54
	These methods allow to cancel draining of unyielded elements.
2022-05-11	Rename `unsigned_offset_from` to `sub_ptr`	Scott McMurray	-1/+1

2022-05-11	Add `unsigned_offset_from` on pointers	Scott McMurray	-1/+1
	Like we have `add`/`sub` which are the `usize` version of `offset`, this adds the `usize` equivalent of `offset_from`. Like how `.add(d)` replaced a whole bunch of `.offset(d as isize)`, you can see from the changes here that it's fairly common that code actually knows the order between the pointers and wants a `usize`, not an `isize`. As a bonus, this can do `sub nuw`+`udiv exact`, rather than `sub`+`sdiv exact`, which can be optimized slightly better because it doesn't have to worry about negatives. That's why the slice iterators weren't using `offset_from`, though I haven't updated that code in this PR because slices are so perf-critical that I'll do it as its own change. This is an intrinsic, like `offset_from`, so that it can eventually be allowed in CTFE. It also allows checking the extra safety condition -- see the test confirming that CTFE catches it if you pass the pointers in the wrong order.
