Required Methods

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

Get the latest committed block id

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

Executes a block.

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

Returns Ok(Result<Vec<Transaction>, Vec<ContractEvents>) if successful, where Vec<Transaction> is a vector of transactions that were kept from the submitted blocks, and Vec<ContractEvents> is a vector of reconfiguration events in the submitted blocks
