pub fn fds_crc32(data: &[u8]) -> u32Expand description
CRC-32/ISO-HDLC (the standard zlib/PNG “CRC-32”) over data.
no_std-friendly (no lookup-table allocation — the polynomial is applied
bitwise); used only at construction time to key the per-game quirk table, so
the per-byte cost is irrelevant to the hot paths. Deterministic by
construction.
