Module event_seq 

Packed event-sequence encoding used by bitmap index storage.

The public cursor/query layers use (tx_seq, event_index). Bitmap storage packs that coordinate into event_seq = (tx_seq << EVENT_BITS) | event_idx.

Constants

EVENT_BITS

Number of low bits of event_seq reserved for the per-tx event index.

MAX_EVENTS_PER_TX

Maximum number of events per tx representable in a packed event_seq.

MAX_TX_SEQ

Maximum tx_seq representable in a packed event_seq.

Functions

decode_event_seq

Unpack a packed event_seq back into (tx_seq, event_idx).

encode_event_seq

Pack (tx_seq, event_idx) into a globally ordered event_seq.

event_seq_lo

Lowest possible event_seq for a given tx_seq (idx 0).

packed_range

Convert semantic event-coordinate bounds into the packed half-open range scanned by bitmap indexes. Accepts any coordinate type that projects to (tx_seq, event_idx), so callers can pass their own position type without this crate knowing about it.
