Modules

node

Traits for configuring a node.

Structs

AnyNodeTypes

A NodeTypes type builder.

AnyNodeTypesWithEngine

A NodeTypesWithEngine type builder.

ForkchoiceStateTracker

The struct that keeps track of the received forkchoice state and their status.

NextBlockEnvAttributes

Traits and helper types used to abstract over EVM methods and types. Represents additional attributes required to configure the next block. This is used to configure the next block’s environment ConfigureEvmEnv::next_cfg_and_block_env and contains fields that can’t be derived from the parent header alone (attributes that are determined by the CL.)

NodeTypesWithDBAdapter

An adapter type combining NodeTypes and db into NodeTypesWithDB.

OnForkChoiceUpdated

Represents the outcome of forkchoice update.

PayloadEvents

Represents a receiver for various payload events.

Enums

BeaconEngineMessage

A message for the beacon engine from other components of the node (engine RPC API invoked by the consensus layer).

BeaconOnNewPayloadError

Represents all error cases when handling a new payload.

EngineApiMessageVersion

The version of Engine API message.

EngineObjectValidationError

Thrown when the payload or attributes are known to be invalid before processing.

Events

Payload builder events.

ForkchoiceStateHash

A helper type to check represent hashes of a [ForkchoiceState]

ForkchoiceStatus

A simplified representation of [PayloadStatusEnum] specifically for FCU.

InvalidPayloadAttributesError

Thrown when validating the correctness of a payloadattributes object.

MessageValidationKind

A type that represents whether or not we are validating a payload or payload attributes.

PayloadBuilderError

Possible error variants during payload building.

PayloadKind

Determines how we should choose the payload to return.

PayloadOrAttributes

Either an [ExecutionPayload] or a types that implements the PayloadAttributes trait.

VersionSpecificValidationError

Thrown when validating an execution payload OR payload attributes fails due to:

Traits

Block

Abstraction of block data type.

BlockBody

Abstraction for block’s body.

BuiltPayload

Represents a built payload type that contains a built [SealedBlock] and can be converted into engine API execution payloads.

ConfigureEvm

Traits and helper types used to abstract over EVM methods and types. Trait for configuring the EVM for executing full blocks.

ConfigureEvmEnv

Traits and helper types used to abstract over EVM methods and types. This represents the set of methods used to configure the EVM’s environment before block execution.

EngineTypes

This type defines the versioned types of the engine API.

EngineValidator

Type that validates the payloads processed by the engine.

FullBlock

Helper trait that unifies all behaviour required by block to support full node operations.

FullNodePrimitives

Helper trait that sets trait bounds on NodePrimitives.

FullProvider

Helper trait to unify all provider traits for simplicity.

FullReceipt

Helper trait that unifies all behaviour required by receipt to support full node operations.

FullSignedTx

Helper trait that unifies all behaviour required by block to support full node operations.

InvalidBlockHook

An invalid block hook.

NodePrimitives

Configures all the primitive types of the node.

NodeTypes

The type that configures the essential types of an Ethereum-like node.

NodeTypesWithDB

A helper trait that is downstream of the NodeTypesWithEngine trait and adds database to the node.

NodeTypesWithEngine

The type that configures an Ethereum-like node with an engine for consensus.

PayloadAttributes

The execution payload attribute type the CL node emits via the engine API. This trait should be implemented by types that could be used to spawn a payload job.

PayloadAttributesBuilder

A builder that can return the current payload attribute.

PayloadBuilder

A type that can request, subscribe to and resolve payloads.

PayloadBuilderAttributes

This can be implemented by types that describe a currently running payload job.

PayloadStoreExt

A helper trait for internal usage to retrieve and resolve payloads.

PayloadTypes

The types that are used by the engine API.

PayloadValidator

Type that validates an [ExecutionPayload].

Functions

validate_parent_beacon_block_root_presence

Validate the presence of the parentBeaconBlockRoot field according to the given timestamp. This method is meant to be used with either a payloadAttributes field or a full payload, with the engine_forkchoiceUpdated and engine_newPayload methods respectively.

validate_payload_timestamp

Validates the timestamp depending on the version called:

validate_version_specific_fields

Validates the presence or exclusion of fork-specific fields based on the ethereum execution payload, or payload attributes, and the message version.

validate_withdrawals_presence

Validates the presence of the withdrawals field according to the payload timestamp. After Shanghai, withdrawals field must be Some. Before Shanghai, withdrawals field must be None;
