Trait that is implemented by a DB that supports certain public (to client) write APIs expected of a Diem DB. This adds write APIs to DbReader.

Required Methods

fn save_transactions( &self, txns_to_commit: &[TransactionToCommit], first_version: Version, ledger_info_with_sigs: Option<&LedgerInfoWithSignatures>, pos_state: Option<PosState>, committed_blocks: Vec<CommittedBlock>, ledger_infos_with_voted_block: Vec<(HashValue, LedgerInfoWithSignatures)> ) -> Result<()>

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

fn save_reward_event( &self, epoch: u64, event: &RewardDistributionEventV2 ) -> Result<()>

fn delete_pos_state_by_block(&self, block_id: &HashValue) -> Result<()>
