Struct Crc32c 

pub struct Crc32c;

CRC-32/ISCSI (Castagnoli), used by iSCSI, SCTP, ext4, and Kafka.

Reflected polynomial 0x82F63B78, initial value and final XOR 0xFFFFFFFF. Check value for b"123456789": 0xE3069283.

Example

use wire_codec::checksum::{Checksum, Crc32c};

assert_eq!(Crc32c.compute(b"123456789"), 0xE306_9283);
