Implementations§

Source§

impl<N, Evm> PayloadProcessor<Evm>
where N: NodePrimitives, Evm: ConfigureEvm<Primitives = N>,

Source

pub fn new( executor: WorkloadExecutor, evm_config: Evm, config: &TreeConfig, precompile_cache_map: PrecompileCacheMap<SpecFor<Evm>>, ) -> Self

Creates a new payload processor.

Source§

impl<N, Evm> PayloadProcessor<Evm>
where N: NodePrimitives, Evm: ConfigureEvm<Primitives = N> + 'static,

Source

pub fn spawn<P, F, I: ExecutableTxIterator<Evm>>( &mut self, env: ExecutionEnv<Evm>, transactions: I, provider_builder: StateProviderBuilder<N, P>, multiproof_provider_factory: F, config: &TreeConfig, ) -> Result<PayloadHandle<WithTxEnv<TxEnvFor<Evm>, I::Tx>, I::Error>, (ParallelStateRootError, I, ExecutionEnv<Evm>, StateProviderBuilder<N, P>)>
where P: BlockReader + StateProviderFactory + StateReader + Clone + 'static, F: DatabaseProviderROFactory<Provider: TrieCursorFactory + HashedCursorFactory> + Clone + Send + 'static,

Spawns all background tasks and returns a handle connected to the tasks.

  • Transaction prewarming task
  • State root task
  • Sparse trie task
§Transaction prewarming task

Responsible for feeding state updates to the multi proof task.

This task runs until:

  • externally cancelled (e.g. sequential block execution is complete)
§Multi proof task

Responsible for preparing sparse trie messages for the sparse trie task. A state update (e.g. tx output) is converted into a multiproof calculation that returns an output back to this task.

Receives updates from sequential execution. This task runs until it receives a shutdown signal, which should be after the block was fully executed.

§Sparse trie task

Responsible for calculating the state root based on the received SparseTrieUpdate.

This task runs until there are no further updates to process.

This returns a handle to await the final state root and to interact with the tasks (e.g. canceling)
