Fields

width: u16

number of bits in the CRC (the degree of the polynomial)

poly: u128

polynomial representation (sans x^width)

init: u128

register initial value before first message bit

refin: bool

if true, reflect input (read bits LSB first)

refout: bool

if true, reflect output

xorout: u128

final CRC is exclusive-or’ed with this

check: u128

CRC of the nine ASCII bytes “123456789”

residue: u128

residue of the CRC

name: String

text description of this CRC
