queryDustEventsDelta
abstract suspend fun queryDustEventsDelta(fromId: Long, timeoutMs: Long = DELTA_TIMEOUT_MS): DustSyncResult
Query dust events starting from a specific event ID (delta sync).
Like queryDustEvents but subscribes from fromId instead of the beginning. Returns structured result with the combined hex, last event ID, and count. If no new events exist (already caught up), returns immediately with empty hex.
Return
Delta sync result with events hex, last applied ID, and event count
Parameters
fromId
First event ID to include (inclusive)
