bytemuck changelog

1.4.2

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

• yanchith fixed the derive checks code to make clippy more happy. PR 45

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
