Struct FactEvent 

pub struct FactEvent {

    pub event_id: FactEventId,
    pub fact_id: FactId,
    pub kind: FactEventKind,
    pub subject: Subject,
    pub predicate: Predicate,
    pub value: Option<FactValue>,
    pub confidence: Confidence,
    pub authority: Authority,
    pub ttl: Ttl,
    pub provenance: Provenance,

}

Fields

event_id: FactEventId

fact_id: FactId

kind: FactEventKind

subject: Subject

predicate: Predicate

value: Option<FactValue>

confidence: Confidence

authority: Authority

ttl: Ttl

provenance: Provenance

evidence: Vec<Evidence>

observed_at: Option<TimestampMillis>

valid_from: Option<TimestampMillis>

valid_to: Option<TimestampMillis>

Valid-time upper bound (ADR 0016): the instant this fact is asserted to stop holding. Read-time freshness treats it like an elapsed TTL. None (the pre-interval default) is skipped during serialization, so events written before this field existed keep byte-identical canonical form and their stored hashes (the ADR 0013 optional-field rule; unlike observed_at/valid_from, which predate it and serialize as explicit nulls).

Implementations

impl FactEvent

pub fn dependency_edges(&self) -> Vec<FactId>

The fact ids this event was derived from — its EvidenceKind::DerivedFrom evidence items, whose locator is the source fact: id (ADR 0010). A malformed locator is skipped (it simply contributes no edge), so this never fails.

impl FactEvent

pub fn validate(&self) -> Result<(), ValidationError>
