pub enum MetaTagDecode {
Absent,
Decoded(RecordedSnapshotMeta),
UnsupportedSchema {
schema: i64,
},
Malformed {
reason: String,
},
}Expand description
What decode_meta_tag found in a snapshot’s tags map. Never an Err: a
bad tag value is repository data and must degrade, not fail a scan.
Variants§
Absent
No kopiur-meta tag on the snapshot (pre-feature or foreign backup).
Decoded(RecordedSnapshotMeta)
A well-formed, supported-schema value.
UnsupportedSchema
A well-formed value written under a schema newer than this reader understands — degrade to recorded-absent (aggregate-count the event).
Malformed
The tag value is present but not decodable (bad JSON, missing/invalid
schema or src). Degrade to recorded-absent (aggregate-count it).
