Crate mycrc 

My CRC

Create your own cyclic redundancy check (CRC).

Getting Started

1. Create your own CRC using CRC::new.
2. Create checksum from message.
   • CRC::checksum
   • CRC::initialize -> CRC::calc_bytes -> … -> CRC::calc_bytes -> CRC::finalize
3. Use CRC::is_error_free_bytes to check if bytes [message + checksum] are error-free.

Example

use mycrc::{CRC, Endian};

// message
const CHECK_BYTES: &[u8] = b"123456789";

// Create your own CRC.
let mut crc32c = CRC::<u32>::new(
    Endian::Little, // endian
    0x1edc6f41, // poly
    0xffffffff, // init
    true, // refin
    true, // refout
    0xffffffff, // xorout
);

// Checksum
assert_eq!(crc32c.checksum(CHECK_BYTES), 0xe3069283);
// Is error-free?
let checksum = crc32c.checksum_to_endian_bytes(CHECK_BYTES);
let bytes = [CHECK_BYTES, &checksum].concat();
assert!(crc32c.is_error_free_bytes(&bytes));
