Implementations

impl MemoryFact

pub fn new( id: FactId, source: EntityId, relation: impl Into<String>, target: EntityId, valid_from: Timestamp, recorded_at: Timestamp, agent_id: AgentId, session_id: SessionId, evidence: Evidence, ) -> Result<Self>

Creates an evidence-carrying temporal relation.

Errors

Rejects invalid relation text or missing evidence.

pub fn valid_until(self, value: Timestamp) -> Result<Self>

Sets the exclusive end of the fact’s valid interval.

Errors

Rejects an end that is not later than valid_from.

pub const fn observed_at(self, value: Timestamp) -> Self

pub const fn with_confidence(self, value: Confidence) -> Self

pub fn supersedes(self, fact: FactId) -> Result<Self>

Links this fact to the historical fact it replaces.

Errors

Rejects self-supersession.

pub fn with_evidence(self, evidence: Evidence) -> Self
