pub fn new() -> Self

Create a new snapshot store with default 5-minute window

pub fn with_window(window_duration: Duration) -> Self

Create a new snapshot store with custom window duration

pub async fn save( &mut self, board: &HypothesisBoard, graph: &BeliefGraph, ) -> SnapshotId

Save current state as a snapshot

pub fn get(&self, id: &SnapshotId) -> Option<&BeliefSnapshot>

Get a snapshot by ID

pub async fn restore( &self, id: &SnapshotId, _board: &Arc<HypothesisBoard>, _graph: &Arc<BeliefGraph>, ) -> Result<()>

Restore state from a snapshot

Clears existing hypotheses and dependencies, then restores from snapshot. Returns error if snapshot not found or expired.

pub fn get_snapshot_data(&self, id: &SnapshotId) -> Result<BeliefSnapshot>

Get snapshot data for restoration (returns owned data)

pub fn list_snapshots(&self) -> Vec<&BeliefSnapshot>

List all active (non-expired) snapshots

pub fn is_expired(&self, id: &SnapshotId) -> bool

Check if a snapshot is expired

pub fn active_count(&self) -> usize

Get the number of active snapshots

pub fn remove(&mut self, id: &SnapshotId) -> bool
