Fingerprint
An FNV-1a pair, fed bytes and numbers, answering sixteen hex characters.

class Fingerprintimport { Fingerprint } from '@driftengine/network';In depth
A class rather than a function over one buffer, because state worth fingerprinting is rarely one buffer: a consumer combines a world, a generator's position and whatever they keep beside both, and the order they feed it in is theirs to fix.
