Struct Fact 

pub struct Fact { /* private fields */ }

Materialized claim backed by at least one evidence record.

Implementations

impl Fact

pub fn new( subject: EntityId, predicate: KnowledgePredicate, value: EvidenceValue, confidence: ConfidenceScore, evidence_id: EvidenceId, ) -> Self

Creates a fact backed by one evidence record.

pub fn with_confidence(self, confidence: ConfidenceScore) -> Self

Replaces the fact confidence score.

pub fn add_evidence(&mut self, evidence_id: EvidenceId)

Adds provenance without counting the same evidence twice.

pub fn id(&self) -> &str

Returns the fact identifier.

pub fn subject(&self) -> &EntityId

Returns the claim subject.

pub fn predicate(&self) -> &KnowledgePredicate

Returns the claim predicate.

pub fn value(&self) -> &EvidenceValue

Returns the claim value.

pub fn confidence(&self) -> ConfidenceScore

Returns the confidence score.

pub fn evidence_ids(&self) -> &BTreeSet<EvidenceId>

Returns the evidence records supporting this fact.

pub fn asserted_at_ms(&self) -> u64

Returns when the fact was asserted in Unix milliseconds.
