Required Methods

fn committed_block_id(&self) -> Result<HashValue, Error>

Get the latest committed block id

fn reset(&self) -> Result<(), Error>

Reset the internal state including cache with newly fetched latest committed block from storage.

fn execute_block( &self, block: (HashValue, Vec<Transaction>), parent_block_id: HashValue ) -> Result<StateComputeResult, Error>

Executes a block.

fn commit_blocks( &self, block_ids: Vec<HashValue>, ledger_info_with_sigs: LedgerInfoWithSignatures ) -> Result<(), Error>

Saves eligible blocks to persistent storage. If we have multiple blocks and not all of them have signatures, we may send them to storage in a few batches. For example, if we have

A <- B <- C <- D <- E

and only C and E have signatures, we will send A, B and C in the first batch, then D and E later in the another batch. Commits a block and all its ancestors in a batch manner.
