pub fn clone_group_fingerprint(
variant: &BuildVariant,
clone_type: CloneClass,
members: &[FragmentFingerprint],
) -> CloneGroupFingerprintExpand description
Fingerprint a clone group from its members’ content fingerprints.
Member fingerprints are sorted and deduplicated first, so the digest is independent of member order and of how many occurrences share identical content: adding another copy of known content leaves the group fingerprint unchanged, while genuinely new member content changes it.
