# `bytemuck` changelog

## 1.6.3

* Small goof with an errant `;`, so [PR 69](https://github.com/Lokathor/bytemuck/pull/69)
  *actually* got things working on SPIR-V.

## 1.6.2

cargo upload goof! ignore this one.

## 1.6.1

* [DJMcNab](https://github.com/DJMcNab) did a fix so that the crate can build for SPIR-V
  [PR 67](https://github.com/Lokathor/bytemuck/pull/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](https://github.com/LU15W1R7H) for doing
  [PR 58](https://github.com/Lokathor/bytemuck/pull/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](https://github.com/zakarumych) got the work started in
  [PR 59](https://github.com/Lokathor/bytemuck/pull/59),
  and [chorman0773](https://github.com/chorman0773) finished off the task in
  [PR 63](https://github.com/Lokathor/bytemuck/pull/63)

## 1.5.1

* Fix `bytes_of` failing on zero sized types.
  [PR 53](https://github.com/Lokathor/bytemuck/pull/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](https://github.com/Lokathor/bytemuck/pull/50)

## 1.4.2

* [Kimundi](https://github.com/Kimundi) fixed an issue that could make `try_zeroed_box`
stack overflow for large values at low optimization levels.
[PR 43](https://github.com/Lokathor/bytemuck/pull/43)

## 1.4.1

* [thomcc](https://github.com/thomcc) fixed up the CI and patched over a soundness hole in `offset_of!`.
[PR 38](https://github.com/Lokathor/bytemuck/pull/38)

## 1.4

* [icewind1991](https://github.com/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](https://github.com/Lokathor/bytemuck/pull/24).
* [HeroicKatora](https://github.com/HeroicKatora) added the
  `try_zeroed_slice_box` function
  [#10](https://github.com/Lokathor/bytemuck/pull/17). `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](https://github.com/thomcc) added many things:
  * A fully sound `offset_of!` macro
    [#10](https://github.com/Lokathor/bytemuck/pull/10)
  * A `Contiguous` trait for when you've got enums with declared values
    all in a row [#12](https://github.com/Lokathor/bytemuck/pull/12)
  * A `TransparentWrapper` marker trait for when you want to more clearly
    enable adding and removing a wrapper struct to its inner value
    [#15](https://github.com/Lokathor/bytemuck/pull/15)
  * Now MIRI is run on CI in every single push!
    [#16](https://github.com/Lokathor/bytemuck/pull/16)

## 1.1.0

* [SimonSapin](https://github.com/SimonSapin) added `from_bytes`,
  `from_bytes_mut`, `try_from_bytes`, and `try_from_bytes_mut` ([PR
  Link](https://github.com/Lokathor/bytemuck/pull/8))

## 1.0.1

* Changed to the [zlib](https://opensource.org/licenses/Zlib) license.
* Added much more proper documentation.
* Reduced the minimum Rust version to 1.34
