Struct LearningHistoryStore 

pub struct LearningHistoryStore { /* private fields */ }

Persistent storage for learning history

Implementations

impl LearningHistoryStore

pub fn new(db: Arc<DB>) -> Self

Create a new learning history store

pub fn record(&self, user_id: &str, event: &ConsolidationEvent) -> Result<()>

Record a significant learning event

pub fn events_since( &self, user_id: &str, since: DateTime<Utc>, ) -> Result<Vec<StoredLearningEvent>>

Query learning events since a timestamp

pub fn events_in_range( &self, user_id: &str, since: DateTime<Utc>, until: DateTime<Utc>, ) -> Result<Vec<StoredLearningEvent>>

Query learning events in a time range

pub fn events_for_memory( &self, user_id: &str, memory_id: &str, limit: usize, ) -> Result<Vec<StoredLearningEvent>>

Get learning events for a specific memory

pub fn events_for_fact( &self, user_id: &str, fact_id: &str, limit: usize, ) -> Result<Vec<StoredLearningEvent>>

Get learning events for a specific fact

pub fn memory_learning_velocity( &self, user_id: &str, memory_id: &str, window_hours: i64, ) -> Result<LearningVelocity>

Calculate learning velocity for a memory

Returns a velocity score based on recent learning activity. Higher velocity = more actively being learned = more relevant.

pub fn fact_learning_velocity( &self, user_id: &str, fact_id: &str, window_days: i64, ) -> Result<LearningVelocity>

Calculate learning velocity for a fact

pub fn stats(&self, user_id: &str) -> Result<LearningStats>

Get aggregated learning statistics

pub fn has_recent_learning( &self, user_id: &str, memory_id: &str, hours: i64, ) -> Result<bool>

Check if a memory has recent learning activity

Used for retrieval boosting - recently learned memories are more relevant

pub fn recency_boost(&self, user_id: &str, memory_id: &str) -> Result<f32>

Get the recency boost factor for a memory

Returns a multiplier (1.0 = no boost, up to ~1.3 for very active learning)

pub fn fact_recency_boost(&self, user_id: &str, fact_id: &str) -> Result<f32>

Get recency boost for a fact

pub fn prune_old_events(&self, user_id: &str, keep_days: i64) -> Result<usize>

Prune old learning history (keep last N days)
