EventCacheStateRecord class

Lean derived cache metadata for one event.

This intentionally does not embed the full Nip01Event. It persists only the extra state useful for cache maintenance tasks such as eviction planning.

Constructors

EventCacheStateRecord({required String eventId, required String pubKey, required int kind, required int createdAt, String? coordinateKey, required bool isCurrent, int? expirationAt, String? deletedByEventId})

const

EventCacheStateRecord.fromJson(Map<String, dynamic> json)

Static Methods

buildForEvents(List<Nip01Event> rawEvents, {int? now}) → List<EventCacheStateRecord>

Builds derived state records from raw events using the same visibility semantics as cache reads and eviction planning.

conflictKeyFor(Nip01Event event) → String?

The NIP-01 conflict domain of event: kind:pubkey:d-tag for addressable kinds, kind:pubkey for other replaceable kinds, null for the rest.

deletionCoversConflictKey(Nip01Event deletion, String conflictKey) → bool

Whether deletion covers conflictKey through one of its a tags.

normalizeConflictKey(String coordinate) → String?

Normalizes a caller supplied conflict domain so it compares equal to conflictKeyFor.
