bytemuck changelog

1.6.2

• Small goof with an errant ;, so PR 69 actually got things working on SPIR-V.

1.6.1

• DJMcNab did a fix so that the crate can build for SPIR-V PR 67

1.6

• The TransparentWrapper trait now has more methods. More ways to wrap, and now you can "peel" too! Note that we don't call it "unwrap" because that name is too strongly associated with the Option/Result methods. Thanks to LU15W1R7H for doing PR 58
• Min Const Generics! Now there's Pod and Zeroable for arrays of any size when you turn on the min_const_generics crate feature. zakarumych got the work started in PR 59, and chorman0773 finished off the task in PR 63

1.5.1

• Fix bytes_of failing on zero sized types. PR 53

1.5

• Added pod_collect_to_vec, which will gather a slice into a vec, allowing you to change the pod type while also safely ignoring alignment. PR 50

1.4.2

• Kimundi fixed an issue that could make try_zeroed_box stack overflow for large values at low optimization levels. PR 43

1.4.1

• thomcc fixed up the CI and patched over a soundness hole in offset_of!. PR 38

1.4

• icewind1991 has contributed the proc-macros for deriving impls of Pod, TransparentWrapper, Zeroable!! Everyone has been waiting for this one folks! It's a big deal. Just enable the derive cargo feature and then you'll be able to derive the traits on your types. It generates all the appropriate tests for you.
• The zeroable_maybe_uninit feature now adds a Zeroable impl to the MaybeUninit type. This is only behind a feature flag because MaybeUninit didn't exist back in 1.34.0 (the minimum rust version of bytemuck).

1.3.1

• The entire crate is now available under the Apache-2.0 OR MIT license as well as the previous Zlib license #24.
• HeroicKatora added the try_zeroed_slice_box function #10. zeroed_slice_box is also available.
• The offset_of! macro now supports a 2-arg version. For types that impl Default, it'll just make an instance using default and then call over to the 3-arg version.
• The PodCastError type now supports Hash and Display. Also if you enable the extern_crate_std feature then it will support std::error::Error.
• We now provide a TransparentWrapper<T> impl for core::num::Wrapper<T>.
• The error type of try_from_bytes and try_from_bytes_mut when the input isn't aligned has been corrected from being AlignmentMismatch (intended for allocation casting only) to TargetAlignmentGreaterAndInputNotAligned.

1.3.0

• Had a bug because the CI was messed up! It wasn't soundness related, because it prevented the crate from building entirely if the extern_crate_alloc feature was used. Still, this is yanked, sorry.

1.2.0

• thomcc added many things:
  • A fully sound offset_of! macro #10
  • A Contiguous trait for when you've got enums with declared values all in a row #12
  • A TransparentWrapper marker trait for when you want to more clearly enable adding and removing a wrapper struct to its inner value #15
  • Now MIRI is run on CI in every single push! #16

1.1.0

• SimonSapin added from_bytes, from_bytes_mut, try_from_bytes, and try_from_bytes_mut (PR Link)

1.0.1

• Changed to the zlib license.
• Added much more proper documentation.
• Reduced the minimum Rust version to 1.34
