Structs

• AddOns
  Additional node extensions.
• AnyNodeTypes
  A NodeTypes type builder.
• AnyNodeTypesWithEngine
  A NodeTypesWithEngine type builder.
• BuilderContext
  Captures the necessary context for building the components of the node.
• DefaultNodeLauncher
  The default launcher for a node.
• EngineNodeLauncher
  The engine node launcher.
• ExExLauncher
  Can launch execution extensions.
• FullNodeTypesAdapter
  An adapter type that adds the builtin provider type to the user configured node types.
• LaunchContext
  Reusable setup for launching a node.
• NextBlockEnvAttributes
  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.)
• NodeAdapter
  Container for the node’s types and the components and other internals that can be used by addons of the node.
• NodeBuilder
  Declaratively construct a node.
• NodeBuilderWithComponents
  A fully type configured node builder.
• NodeBuilderWithTypes
  A node builder that also has the configured types.
• NodeConfig
  This includes all necessary configuration to launch the node. The individual configuration options can be overwritten before launching the node.
• NodeHandle
  A Handle to the launched node.
• NodeTypesAdapter
  Container for the node’s types and the database the node uses.
• NodeTypesWithDBAdapter
  An adapter type combining NodeTypes and db into NodeTypesWithDB.
• PayloadEvents
  Represents a receiver for various payload events.
• RpcAddOns
  Captures node specific addons that can be installed on top of the type configured node and are required for launching the node, such as RPC.
• WithLaunchContext
  A NodeBuilder with it’s launch context already configured.

Enums

• 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.
• MessageValidationKind
  A type that represents whether or not we are validating a payload or payload attributes.
• PayloadBuilderError
  Possible error variants during payload building.
• 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

• BuilderProvider
  Returns the builder for type.
• BuiltPayload
  Represents a built payload type that contains a built [SealedBlock] and can be converted into engine API execution payloads.
• ConfigureEvm
  Trait for configuring the EVM for executing full blocks.
• ConfigureEvmEnv
  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 sent to the engine.
• EthApiTypes
  Network specific eth API types.
• FullNodeComponents
  Encapsulates all types and components of the node.
• FullNodeTypes
  A helper trait that is downstream of the NodeTypesWithEngine trait and adds stateful components to the node.
• FullProvider
  Helper trait to unify all provider traits for simplicity.
• InvalidBlockHook
  An invalid block hook.
• LaunchNode
  A general purpose trait that launches a new node of any kind.
• 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 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.
• PayloadBuilderConfig
  Re-export the core configuration traits. A trait that provides payload builder settings.
• PayloadTypes
  The types that are used by the engine API.
• RethNetworkConfig
  Re-export the core configuration traits. A trait that represents the configured network and can be used to apply additional configuration to the network.
• RethTransactionPoolConfig
  Re-export the core configuration traits. A trait that provides all basic config values for the transaction pool and is implemented by the TxPoolArgs type.

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;

Type Aliases

• EthApiBuilderCtx
  Alias for [reth_rpc_eth_types::EthApiBuilderCtx], adapter for FullNodeComponents.
• RethFullAdapter
  The adapter type for a reth node with the builtin provider type
