Provided methods

fn save_transactions(
    &self,
    txns_to_commit: &[TransactionToCommit],

    ledger_info_with_sigs: Option<&LedgerInfoWithSignatures>
) -> Result<()>

Persist transactions. Called by the executor module when either syncing nodes or committing blocks during normal operation. See DiemDB::save_transactions.

fn get_state_snapshot_receiver(
    &self,
    version: Version,
