Returns the execution payload bodies by the range starting at start, containing count blocks.

WARNING: This method is associated with the BeaconBlocksByRange message in the consensus layer p2p specification, meaning the input should be treated as untrusted or potentially adversarial.

Implementers should take care when acting on the input to this method, specifically ensuring that the range is limited properly, and that the range boundaries are computed correctly and without panics.

fn exchange_transition_configuration<'life0, 'async_trait>( &'life0 self, transition_configuration: TransitionConfiguration, ) -> Pin<Box<dyn Future<Output = RpcResult<TransitionConfiguration>> + Send + 'async_trait>>

Note: This method will be deprecated after the cancun hardfork:

Consensus and execution layer clients MAY remove support of this method after Cancun. If no longer supported, this method MUST be removed from the engine_exchangeCapabilities request or response list depending on whether it is consensus or execution layer client.

Source

fn get_client_version_v1<'life0, 'async_trait>( &'life0 self, client_version: ClientVersionV1, ) -> Pin<Box<dyn Future<Output = RpcResult<Vec<ClientVersionV1>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

This function will return the ClientVersionV1 object. See also: https://github.com/ethereum/execution-apis/blob/03911ffc053b8b806123f1fc237184b0092a485a/src/engine/identification.md#engine_getclientversionv1make fmt

  • When connected to a single execution client, the consensus client MUST receive an array with a single ClientVersionV1 object.
  • When connected to multiple execution clients via a multiplexer, the multiplexer MUST concatenate the responses from each execution client into a single, flat array before returning the response to the consensus client.

Fetch blobs for the consensus layer from the in-memory blob cache.

Provided Methods§

Source

fn into_rpc(self) -> RpcModule<Self>
where Engine::PayloadAttributes: DeserializeOwned,

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
