Function cdrom_crc::crc16

pub fn crc16(data: &[u8], initial_crc: u16) -> u16

Calculates a 16-bit CRC for the supplied data. This is the form of CRC used by the CD standard's Q subcode data. initial_crc is an initial CRC value which will be updated as calculations are performed; for Q subcode data, use the value of the CRC16_INITIAL_CRC constant.

Example

use cdrom_crc::{crc16, CRC16_INITIAL_CRC};

let result = crc16(&[0, 1, 2, 3], CRC16_INITIAL_CRC);
assert_eq!(result, 0x9ECE);

Notes

This form of CRC is defined in section 22.3.6 of the CD-ROM standard (ECMA-130, the “Yellow Book”).
