Trait to define the interface for how the REST service interacts with a QuorumDriver or a simulated transaction executor.

Required Methods

fn execute_transaction<'life0, 'async_trait>( &'life0 self, request: ExecuteTransactionRequestV1, skip_certification: bool, client_addr: Option<SocketAddr>, ) -> Pin<Box<dyn Future<Output = Result<ExecuteTransactionResponseV1, QuorumDriverError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn simulate_transaction( &self, transaction: TransactionData, checks: VmChecks, ) -> Result<SimulateTransactionResult, IotaError>

fn wait_for_checkpoint_inclusion<'life0, 'life1, 'async_trait>( &'life0 self, digests: &'life1 [TransactionDigest], timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<BTreeMap<TransactionDigest, (CheckpointSequenceNumber, u64)>, IotaError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Wait for the given transactions to be included in a checkpoint.

Returns a mapping from transaction digest to (checkpoint_sequence_number, checkpoint_timestamp_ms). On timeout, returns partial results for any transactions that were already checkpointed.

Provided Methods

fn read_transaction_from_cache( &self, digest: &TransactionDigest, include_events: bool, include_input_objects: bool, include_output_objects: bool, ) -> Result<Option<CachedTransactionData>, IotaError>

Read authoritative effects, events, and input/output objects for a locally-executed transaction from the cache. Used by callers that have already waited for checkpoint inclusion and want to discard any uncertified single-validator copies.

Returns Ok(None) if the tx is not in the cache, or if the executor does not maintain a local cache (e.g. simulacrum).
