Module query_options

Structs§

IntraTxCoordinate: Intra-transaction coordinate: a transaction and an index within it (events today; any per-transaction-indexed lane). Boundary cursors may point at slots with no item.
QueryOptions: Validated, normalized form of QueryOptions (the proto wire type).
ResolvedCheckpointRange: A request’s checkpoint window resolved into the checkpoint-sequence interval to scan. Cursors do not narrow it: ResolvedScan::resolve applies them by scan position. Unlike ResolvedScan<u64>/ResolvedScan<IntraTxCoordinate>, the scan domain here is checkpoint space, so the entry and terminal checkpoints derive from range directly and need no extra fields.
ResolvedScan: A request’s checkpoint bounds resolved into the scan-position interval to scan, along with the checkpoint-space facts for watermark rendering.
ScanBounds: Semantic scan bounds over explicit scan positions (cursor trims need exclusive bounds on either side).

Ordering
RangeExhaustion: Why a resolved scan interval is exhausted. Fixed at range-resolution time, carried through scan state, and rendered by ScanTerminal.

ScanCursor: How a lane reads wire cursors: the token’s coordinate in the lane’s position space.
ScanPosition: A scan position with a successor, so scan bounds can tell exactly whether they admit any position.

below_serving_floor: The error for a request that needs data below this server’s serving floor, whose lowest available checkpoint is floor_checkpoint: that data is pruned and permanently gone.
validate_checkpoint_bounds: The requested checkpoint window’s validity check, standalone so backends can sequence it independently of options parsing (kv validates bounds before the read mask and options; the fused resolution re-runs it harmlessly).
