Struct Crc32 

pub struct Crc32;

CRC-32/ISO-HDLC, the CRC-32 of IEEE 802.3, zlib, gzip, and PNG.

Reflected polynomial 0xEDB88320, initial value and final XOR 0xFFFFFFFF. Check value for b"123456789": 0xCBF43926.

Example

use wire_codec::checksum::{Checksum, Crc32};

assert_eq!(Crc32.compute(b"123456789"), 0xCBF4_3926);
