Implementations§

Source§

impl<P, E, T, Spec> EngineApiTreeHandler<P, E, T, Spec>
where P: DatabaseProviderFactory + BlockReader + StateProviderFactory + StateReader + Clone + 'static, <P as DatabaseProviderFactory>::Provider: BlockReader, E: BlockExecutorProvider, T: EngineTypes, Spec: Send + Sync + EthereumHardforks + 'static,

Source

pub fn new( provider: P, executor_provider: E, consensus: Arc<dyn Consensus>, payload_validator: ExecutionPayloadValidator<Spec>, outgoing: UnboundedSender<EngineApiEvent>, state: EngineApiTreeState, canonical_in_memory_state: CanonicalInMemoryState, persistence: PersistenceHandle, persistence_state: PersistenceState, payload_builder: PayloadBuilderHandle<T>, config: TreeConfig, engine_kind: EngineApiKind, ) -> Self

Creates a new EngineApiTreeHandler.

Source

pub fn spawn_new( provider: P, executor_provider: E, consensus: Arc<dyn Consensus>, payload_validator: ExecutionPayloadValidator<Spec>, persistence: PersistenceHandle, payload_builder: PayloadBuilderHandle<T>, canonical_in_memory_state: CanonicalInMemoryState, config: TreeConfig, invalid_block_hook: Box<dyn InvalidBlockHook>, kind: EngineApiKind, ) -> (Sender<FromEngine<EngineApiRequest<T>>>, UnboundedReceiver<EngineApiEvent>)

Creates a new EngineApiTreeHandler instance and spawns it in its own thread.

Returns the sender through which incoming requests can be sent to the task and the receiver end of a EngineApiEvent unbounded channel to receive events from the engine.

Source

pub fn sender(&self) -> Sender<FromEngine<EngineApiRequest<T>>>

Returns a new Sender to send messages to this type.

Source

pub fn run(self)

Run the engine API handler.

This will block the current thread and process incoming messages.

Source

pub fn find_canonical_header( &self, hash: B256, ) -> Result<Option<SealedHeader>, ProviderError>

Attempts to find the header for the given block hash if it is canonical.
