v0.0.9

[0.0.9] - 2022-07-25

Features

Rework TwoSimdBlocks into Twice

• TwoSimdBlocks got removed
• Twice<A> gives an alignment guarantee of two blocks of A
• halves on aligned block of Twice<A> splits a block into two smaller alignments

v0.0.8

[0.0.8] - 2022-07-09

Features

Make Default conform to strict provenance.

Related: #34

Made Alignment types empty.

Related: #31

Bug Fixes

Invalid Hash impl for AlignedBytes.

Related: #33

v0.0.7

[0.0.7] - 2022-06-03

Features

alignment_size function for aligned types.

• Allows getting the alignment size as a method instead of static.

Related: #29

v0.0.6

[0.0.6] - 2022-05-28

Bug Fixes

Take FnMut in new_initialize.

• Fn is unnecessarily prohibitive, FnMut allows more initialisation functions.

v0.0.5

[0.0.5] - 2022-05-27

Features

Add support for AVX512.

• When the avx512f target feature is enabled the SimdBlock is set to 64 bytes.

Reliability

Enable local simd-size-matrix tests.

• One can use the test_simd_sizes.py script to run the simd-size test matrix locally.

v0.0.4

[0.0.4] - 2022-05-25

Features

Support sse target feature.

• When the sse target feature is enabled
  on x86/x86_64 the SimdBlock size is 16 bytes,
  unless a target feature with a larger vector is also enabled.

Related: #18

Reliability

Miri test on windows targets.

Added simd_alignment_test.

• Test whether the size of SimdBlock agrees with the expected one
  for a given target.

Added simd-size-matrix test.

• Use simd_alignment_test to check whether SimdBlock sizes
  remain consistent across targets.

v0.0.3

[0.0.3] - 2022-05-18

Bug Fixes

Impl of Default returning unaligned ptrs.

• Implementations of Default for
• AlignedBytes
• &AlignedSlice
• &mut AlignedSlice
• were incorrect by using NonNull::dangling as the pointer.
• That pointer need not be aligned to the specified Alignment.
• This was fixed by using std's dangling implementation tweaked to
• the required alignment, while still not allocating.

Related: #11

Reliability

Allow miri symbolic-alignment-check.

• Miri's -Zmiri-symbolic-alignment-check breaks align_offset to always return usize::MAX (that is by design), so we need to fallback to regular cast-then-modulo alignment check for tests when running under Miri.

v0.0.2

[0.0.2] - 2022-05-17

Features

Added alignment::TwoTo<N>.

v0.0.1

[0.0.1] - 2022-05-17

Features

Initial API.

• Alignment types driven by the alignment module.
• AlignedBytes -- aligned container
• AlignedSlice -- type guarantee on alignment of &[u8]
• AlignedBlockIterator -- iterate aligned blocks of a slice.
• Quality of life implementations of Deref and std::cmp traits.
