CRC32C

Rust implementation of the CRC-32-Castagnoli algorithm. If you have SSE 4.2 enabled at compile time, it will only build the SSE implementation. Otherwise, it will build both versions, and use cpuid to choose the best implementation at run time.

The code is inspired by Mark Adler's CRC32C implementation.

Usage

First, add this to your Cargo.toml:

[dependencies]
crc32c = "0.4"

extern crate crc32c;

fn main() {
    let message = b"Hello world!";
    let crc = crc32c::crc32c(message);

    println!("hash = {}", crc);
}
