http://git.dreamy.place/mirrors/rust/atom?h=1.76.02024-01-25T19:40:56+00:00fix: Drop guard was deallocating with the incorrect size2024-01-25T19:40:56+00:00The 8472git@infinite-source.de2024-01-19T21:42:52+00:00urn:sha1:73b36b14042351b55fcce7afc196669a5bc84c09
InPlaceDstBufDrop holds onto the allocation before the shrinking happens
which means it must deallocate the destination elements but the source
allocation.

remove alignment-changing in-place collect2024-01-25T19:40:51+00:00The 8472git@infinite-source.de2024-01-18T21:50:14+00:00urn:sha1:e55be1a711e36f1057d54add574ec1b5ca3f9fdb
Currently stable users can't benefit from this because GlobaAlloc doesn't support
alignment-changing realloc and neither do most posix allocators.
So in practice it always results in an extra memcpy.

add more niches to rawvec
Previously RawVec only had a single niche in its `NonNull` pointer. With this change it now has `isize::MAX` niches since half the value-space of the capacity field is never needed, we can't have a capacity larger than isize::MAX.

Add lint against ambiguous wide pointer comparisons
This PR is the resolution of https://github.com/rust-lang/rust/issues/106447 decided in https://github.com/rust-lang/rust/issues/117717 by T-lang.
## `ambiguous_wide_pointer_comparisons`
*warn-by-default*
The `ambiguous_wide_pointer_comparisons` lint checks comparison of `*const/*mut ?Sized` as the operands.
### Example
```rust
let ab = (A, B);
let a = &ab.0 as *const dyn T;
let b = &ab.1 as *const dyn T;
let _ = a == b;
```
### Explanation
The comparison includes metadata which may not be expected.
-------
This PR also drops `clippy::vtable_address_comparisons` which is superseded by this one.
~~One thing: is the current naming right? `invalid` seems a bit too much.~~
