It seems like a copy-paste error has happened between `try_from_bytes`/`try_from_bytes_mut` and `try_pod_read_unaligned`, causing `internal::try_pod_read_unaligned` to try to read a &T::Bits instead of a T::Bits, usually failing with a `SizeMismatch` error. In the worst case, this allows UB in safe code by having a type allowing any bit pattern and being pointer-sized.
* Add `allocation::{try_,}cast_{arc,rc}`, and add `{wrap,peel}_{arc,rc}` to `TransparentWrapperAlloc`.
* Avoid intermediate slice reference in `try_cast_slice_{arc,rc}`.
* remove `unsafe` block; run `cargo +nightly fmt` (ignoring files I didn't modify)
* Make `cast_rc` (etc) have the same bounds as `cast_mut`, due to the existence of `Rc::get_mut_unchecked`.
* add `try_zeroed_vec` and `zeroed_vec`, adjust impl of `try_zeroed_slice_box`
* go back to returning an error rather than calling handle_alloc_error
* use boxed slice .into_vec instead :)
* same as Zeroable and Pod but for types which are Zeroable and Pod when
wrapped in Option
* allows downstream users to implement Zeroable and Pod for their own
Option<T> types without running into orphan rules
Normal Miri does not provide sufficient safety guarantees. Using the flag `-Zmiri-tag-raw-pointers` also checks usage of pointers in a more strict way.
* Added try_cast_slice_box and cast_slice_box
* Modified try_cast_slice_box and try_cast_vec to recalculate the length if the change in size between the two types is valid.
* Ran cargo format
* allow deriving traits on unions in some cases
* basic union tests for nopadding and anybitpattern
* implement derives for unions for more traits
* remove Pod and AnyBitPattern derives for unions due to possible unsoundness
* add MaybePod and NoPadding traits
* MaybePod and NoPadding derive macros
* fix doctest
* fmt
* fix bad doc link
* move new casting functions into separate modules
* fmt
* fix doctest and derive test
* remove relaxed module, add anybitpattern
* rename MaybePod to CheckedCastFromPod
* rename checked casting functions
* rework CheckedCastFromPod into CheckedBitPattern
* add anybitpattern derive, fix up other derives
* fix doctest
* fix derive trait of bits type
* export AnyBitPattern derive
* export anybitpattern from traits
* actually export derive macro for AnyBitPattern
* make bits struct pub because of type leaking rules
* allow clippy lint in derive
* add copy bound to CheckedBitPattern
* - replace Pod bounds with NoPadding+AnyBitPattern
- add try and panic versions of checked cast functions
- slightly update docs
* fix derive tests
* - adapt the allocation module cast functions as well
- as part of that, make AnyBitPattern a subtrait of Zeroable
- AnyBitPattern derive also derives Zeroable
* @JakobDegen and @zakarumych nits
* superset -> subset on CheckedBitPattern and NoPadding docs
* derive Debug on generated `Bits` structs, which can be useful for debugging failures
* don't derive debug on spirv target arch
* make it work on 1.34
* merge conflicts
* fix erroneous behavior in doctest
