Runtime transaction dispatcher trait.

It defines the interface used by the runtime call dispatcher to process transactions.

Required Methods

fn execute_batch( &self, ctx: Context<'_>, batch: &TxnBatch, in_msgs: &[IncomingMessage] ) -> Result<ExecuteBatchResult, RuntimeError>

Execute the transactions in the given batch.

Consensus Layer State Integrity

Before this method is invoked, consensus layer state integirty verification is performed.

fn check_batch( &self, ctx: Context<'_>, batch: &TxnBatch ) -> Result<Vec<CheckTxResult>, RuntimeError>

Check the transactions in the given batch for validity.

Consensus Layer State Integrity

No consensus layer state integrity verification is performed for queries by default. The runtime dispatcher implementation should perform integrity verification if needed on a query-by-query basis.

Provided Methods

fn schedule_and_execute_batch( &self, _ctx: Context<'_>, _initial_batch: &mut TxnBatch, _in_msgs: &[IncomingMessage] ) -> Result<ExecuteBatchResult, RuntimeError>

Schedule and execute transactions in the given batch.

The passed batch is an initial batch. In case the runtime needs additional items it should request them from the host.

Consensus Layer State Integrity

Before this method is invoked, consensus layer state integirty verification is performed.

fn finalize(&self, _new_storage_root: Hash)

Invoke the finalizer (if any).

fn set_abort_batch_flag(&mut self, _abort_batch: Arc<AtomicBool>)

Configure abort batch flag.

fn query( &self, _ctx: Context<'_>, _method: &str, _args: Vec<u8> ) -> Result<Vec<u8>, RuntimeError>

Process a query.

Consensus Layer State Integrity

No consensus layer state integrity verification is performed for queries by default. The runtime dispatcher implementation should perform integrity verification if needed on a query-by-query basis.
