Struct QueryMemoryUseCase 

pub struct QueryMemoryUseCase<P, V>
where
    P: PersistencePort + Send + Sync + 'static,
    V: VectorPort + Send + Sync + 'static,
{ /* private fields */ }

Use-case: query the canonical belief for a (subject, predicate) line. Generic over persistence and vector ports. Vector is optional: None = structural-only mode (v0.1 default).

Implementations

impl<P, V> QueryMemoryUseCase<P, V>

where P: PersistencePort + Send + Sync + 'static, V: VectorPort + Send + Sync + 'static,

pub fn new( persistence: Arc<P>, vector: Option<Arc<V>>, config: EngineConfig, ) -> Self

pub fn execute_with_time( &self, req: QueryMemoryRequest, now: DateTime<Utc>, ) -> Result<QueryMemoryResponse, MemError>

Read path: no Txn (read-only). TruthEngine fold → Projection → DTO.

now is injected by the EngineHandle (DETERMINISM — no clock reads here).

pub fn execute( &self, req: QueryMemoryRequest, ) -> Result<QueryMemoryResponse, MemError>

Convenience wrapper that stamps now internally (for direct calls outside EngineHandle).
