Required Associated Types

type DeltaDb: DeltaDbTrait

Required Methods

fn get_delta_db_dir(&self) -> &Path

fn get_delta_db_name(&self, snapshot_epoch_id: &EpochId) -> String

fn get_delta_db_path(&self, delta_db_name: &str) -> PathBuf

fn new_empty_delta_db(&self, delta_db_name: &str) -> Result<Self::DeltaDb>

fn get_delta_db(&self, delta_db_name: &str) -> Result<Option<Self::DeltaDb>>

fn destroy_delta_db(&self, delta_db_name: &str) -> Result<()>

Destroy a Delta DB. Keep in mind that this method is irrecoverable. Ref-counting is necessary for Delta1 MPT in Snapshot.

Provided Methods

fn scan_persist_state( &self, snapshot_info_map: &HashMap<EpochId, SnapshotInfo> ) -> Result<(Vec<EpochId>, HashMap<EpochId, Self::DeltaDb>)>
