univeral-hashUniversal Hash Function (UHF) crateUniversal Hash Function (UHF) crate
Description
SIMD implementations of UHFs are able to process multiple input blocks in parallel. However UniversalHash::update
only processes one-block-at-a-time.
There's some precedent for parallel block processing in the block-cipher
crate, which has an associated ParBlocks
type-level constant which signals how many blocks a given implementation can process in parallel:
https://docs.rs/block-cipher/0.8.0/block_cipher/trait.BlockCipher.html#associatedtype.ParBlocks
I believe @newpavlov wanted to make some changes to how that works, but regardless, universal-hash
should have similar support for processing multiple blocks in parallel in SIMD contexts
