Modules

engine

Traits, validation methods, and helper types used to abstract over engine types.

node

Traits for configuring a node.

payload

This crate defines abstractions to create and update payloads (blocks)

payload_builder

This crate defines abstractions to create and update payloads (blocks)

Structs

AddOnsContext

Context passed to NodeAddOns::launch_add_ons,

AnyNodeTypes

A NodeTypes type builder.

AnyNodeTypesWithEngine

A NodeTypes type builder.

BeaconConsensusEngineHandle

A cloneable sender type that can be used to send engine API messages.

ForkchoiceStateTracker

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

FullNodeTypesAdapter

An adapter type that adds the builtin provider type to the user configured node types.

NextBlockEnvAttributes

Represents additional attributes required to configure the next block. This is used to configure the next block’s environment ConfigureEvm::next_evm_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.

TreeConfig

The configuration of the engine tree.

Enums

BeaconConsensusEngineEvent

Events emitted by the consensus engine.

BeaconEngineMessage

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

BeaconForkChoiceUpdateError

Represents error cases for an applied forkchoice update.

BeaconOnNewPayloadError

Represents all error cases when handling a new payload.

ConsensusEngineLiveSyncProgress

Progress of the consensus engine during live sync.

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.

NewPayloadError

Error validating payload received over newPayload API.

PayloadBuilderError

Possible error variants during payload building.

PayloadKind

Determines how we should choose the payload to return.

PayloadOrAttributes

Either a type that implements the ExecutionPayload or a type that implements the PayloadAttributes trait.

VersionSpecificValidationError

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

Constants

DEFAULT_MAX_PROOF_TASK_CONCURRENCY

Default maximum concurrency for proof tasks

DEFAULT_MEMORY_BLOCK_BUFFER_TARGET

How close to the canonical head we persist blocks.

DEFAULT_PERSISTENCE_THRESHOLD

Triggers persistence when the number of canonical blocks in memory exceeds this threshold.

DEFAULT_RESERVED_CPU_CORES

Default number of reserved CPU cores for non-reth processes.

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

A complete configuration of EVM for Reth.

EngineTypes

This type defines the versioned types of the engine API based on the ethereum engine API.

EngineValidator

Type that validates the payloads processed by the engine.

ExecutionPayload

An execution payload.

FullBlock

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

FullNodeComponents

Encapsulates all types and components of the node.

FullNodePrimitives

Helper trait that sets trait bounds on NodePrimitives.

FullNodeTypes

A helper trait that is downstream of the NodeTypes trait and adds stateful components to the node.

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.

NodeAddOns

Customizable node add-on types.

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 NodeTypes trait and adds database to the node.

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.

PayloadBuilderAttributes

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

PayloadBuilderFor

Helper trait to bound [PayloadBuilder] to the node’s engine types.

PayloadTypes

The types that are used by the engine API.

PayloadValidator

Type that validates an ExecutionPayload.

Functions

has_enough_parallelism

Determines if the host has enough parallelism to run the payload processor.

validate_execution_requests

Validates that execution requests are valid according to Engine API specification.

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;
