§crc
Rust implementation of CRC.
§Examples
Using a well-known algorithm:
const X25: crc::Crc<u16> = crc::Crc::<u16>::new(&crc::CRC_16_IBM_SDLC);
assert_eq!(X25.checksum(b"123456789"), 0x906e);Using a custom algorithm:
const CUSTOM_ALG: crc::Algorithm<u16> = crc::Algorithm {
width: 16,
poly: 0x8005,
init: 0xffff,
refin: false,
refout: false,
xorout: 0x0000,
check: 0xaee7,
residue: 0x0000
};
let crc = crc::Crc::<u16>::new(&CUSTOM_ALG);
let mut digest = crc.digest();
digest.update(b"123456789");
assert_eq!(digest.finalize(), 0xaee7);Structs§
- This struct describes a CRC algorithm using the fields specified by the Catalogue of parametrised CRC algorithms.
- Implementation using a 256 entry lookup table. Use it with
Crc<Bytewise<W>> - Implementation using no lookup table. Use it with
Crc<NoTable<W>> - Implementation using a 16 * 256 entry lookup table. Use it with
Crc<Slice16<W>>
