Crate crc32fast

Expand description

§Example

use crc32fast::Hasher;

let mut hasher = Hasher::new();
hasher.update(b"foo bar baz");
let checksum = hasher.finalize();

§Performance

This crate contains multiple CRC32 implementations:

  • A fast baseline implementation which processes up to 16 bytes per iteration
  • An optimized implementation for modern x86 using sse and pclmulqdq instructions

Calling the Hasher::new constructor at runtime will perform a feature detection to select the most optimal implementation for the current CPU feature set.

Structs§

    Represents an in-progress CRC32 computation.
