Enum TemporalMode 

Source 
#[repr(u8)]
pub enum TemporalMode {
    AsOf = 0,
    AtTime = 1,
}
Expand description

Temporal snapshot mode for AS OF / AT TIME queries.

Used in Pattern::AsOf and PhysicalOperatorType::AsOf (Phase 4).

Variants§

§

AsOf = 0

Assertion-time snapshot: include quins with prov:generatedAtTime ≤ timestamp_ms.

§

AtTime = 1

Valid-time point: include quins where startedAtTime ≤ t ≤ endedAtTime.
