Module reth::payload

Re-exported payload related types

Modules

• database
  Database adapters for payload building.
• error
  Error types emitted by types or implementations of this crate.
• noop
  A payload builder service task that does nothing.
• test_utilstest-utils
  Utils for testing purposes.

Structs

• EthBuiltPayload
  Contains the built payload.
• EthPayloadBuilderAttributes
  Container type for all components required to build a payload.
• ExecutionPayloadValidator
  Execution payload validator.
• PayloadBuilderHandle
  A communication channel to the PayloadBuilderService.
• PayloadBuilderService
  A service that manages payload building tasks.
• PayloadId
  And 8-byte identifier for an execution payload.
• PayloadStore
  A communication channel to the PayloadBuilderService that can retrieve payloads.

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.
• KeepPayloadJobAlive
  Whether the payload job should be kept alive or terminated after the payload was requested by the CL.
• 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

• BuiltPayload
  Represents a built payload type that contains a built SealedBlock and can be converted into engine API execution payloads.
• 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.
• PayloadBuilderAttributes
  This can be implemented by types that describe a currently running payload job.
• PayloadJob
  A type that can build a payload.
• PayloadJobGenerator
  A type that knows how to create new jobs for creating payloads.
• PayloadTypes
  The types that are used by the engine API.

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;
