pub fn crc8(bytes: &[u8]) -> u8Expand description
Compute CRC-8 with the standard initial value (0x00).
There is no separate “HEM init”: EN 302 755 §5.1.7 puts
crc8(header) XOR MODE on the wire, so HEM (MODE=1) is the init-0 CRC
XOR 1. (A previous revision modelled HEM as init=0xB5 — that value is
init-0 propagated through exactly 9 zero bytes and only coincided for
9-byte inputs; do not reintroduce it.)
