v0.2.0

Summary

Port assembly to Rust and refactor MemZeroizer trait.

Date: 2022-04-12
Version: 0.2.0

Changelog

Added

• X86_64 SSE2 and AVX simd zeroizers using inline assembly.
• nightly_stdsimd and nightly_strict_provenance features. Both don't affect
  the library interface currently.

Changed

• Ported AsmRepStosZeroizer to use Rust inline assembly rather than C inline
  assembly so it doesn't require the cc feature and a C compiler anymore.
• MemZeroizer trait, replaced zeroize_mem_minaligned method with new method
  zeroize_mem_blocks which takes the logarithm of the align and in addition a
  logarithm of block size as constant generics (such that len must be a
  multiple of of this block size, and ptr is aligned to the specified align).
• DefaultMemZeroizer now uses one of the simd zeroizers when available and no
  libc zeroizer or nightly compiler (nightly_core_intrinsics feature) is
  available.

Removed

• cc crate feature, since the C inline assembly has been ported to Rust inline assembly.
