pub enum FingerprintStyle {
DefPathHash,
HirId,
Unit,
Opaque,
}
Expand description
Describes the contents of the fingerprint generated by a given query.
Variants§
DefPathHash
The fingerprint is actually a DefPathHash.
HirId
The fingerprint is actually a HirId.
Unit
Query key was ()
or equivalent, so fingerprint is just zero.
Opaque
Some opaque hash.
