Module polkadot_node_subsystem::messages

Re-export of all messages type, including the wrapper type.

Modules

• network_bridge_event
  Network events as transmitted to other subsystems, wrapped in their message types.

Structs

• BlockDescription
  Describes a relay-chain block by the para-chain candidates it includes.
• CanSecondRequest
  A request to the candidate backing subsystem to check whether we can second this candidate.
• CheckedIndirectAssignment
  A checked indirect assignment, the crypto for the cert has been validated and the candidate_bitfield is correctly claimed at delay_tranche.
• CheckedIndirectSignedApprovalVote
  A checked indirect signed approval vote.
• HighestApprovedAncestorBlock
  Response type to ApprovalVotingMessage::ApprovedAncestor.
• HypotheticalMembershipRequest
  Request specifying which candidates are either already included or might become included in fragment chain under a given active leaf (or any active leaf if fragment_chain_relay_parent is None).
• IntroduceSecondedCandidateRequest
  Request introduction of a seconded candidate into the prospective parachains subsystem.
• ProspectiveValidationDataRequest
  A request for the persisted validation data stored in the prospective parachains subsystem.
• ProvisionerInherentData
  Inherent data returned by the provisioner
• ValidationFailed
  Blanket error for validation failing for internal reasons.

Enums

• AllMessages
  Generated message type wrapper over all possible messages used by any subsystem.
• ApprovalCheckError
  The error result type of ApprovalVotingMessage::ImportApproval request.
• ApprovalCheckResult
  The result type of ApprovalVotingMessage::ImportApproval request.
• ApprovalDistributionMessage
  Message to the Approval Distribution subsystem.
• ApprovalVotingMessage
  Message to the Approval Voting subsystem.
• ApprovalVotingParallelMessage
  Message to the approval voting parallel subsystem running both approval-distribution and approval-voting logic in parallel. This is a combination of all the messages ApprovalVoting and ApprovalDistribution subsystems can receive.
• AssignmentCheckError
  The error result type of ApprovalVotingMessage::ImportAssignment request.
• AssignmentCheckResult
  The result type of ApprovalVotingMessage::ImportAssignment request.
• AvailabilityDistributionMessage
  Availability Distribution Message.
• AvailabilityRecoveryMessage
  Availability Recovery Message.
• AvailabilityStoreMessage
  Availability store subsystem message.
• BitfieldDistributionMessage
  Bitfield distribution message.
• BitfieldSigningMessage
  A dummy implementation to satisfy the current internal structure and cannot be constructed delibarately, since it’s not meant to be sent or used at all
• CandidateBackingMessage
  Messages received by the Candidate Backing subsystem.
• CandidateValidationMessage
  Messages received by the Validation subsystem.
• ChainApiMessage
  Chain API request subsystem message.
• ChainSelectionMessage
  Chain selection subsystem messages

  Message to the Collation Generation subsystem.
• CollatorProtocolMessage
  Messages received by the Collator Protocol subsystem.
• DisputeCoordinatorMessage
  Messages received by the dispute coordinator subsystem.
• DisputeDistributionMessage
  Messages going to the dispute distribution subsystem.
• GossipSupportMessage
  Message to the Gossip Support subsystem.
• HypotheticalCandidate
  A hypothetical candidate to be evaluated for potential/actual membership in the prospective parachains subsystem.
• IfDisconnected
  When sending a request, what to do on a disconnected recipient.
• ImportStatementsResult
  The result of DisputeCoordinatorMessage::ImportStatements.
• NetworkBridgeEvent
  Events from network.
• NetworkBridgeRxMessage
  Messages received from other subsystems.
• NetworkBridgeTxMessage
  Messages received from other subsystems by the network bridge subsystem.
• ParentHeadData
  The parent head-data hash with optional data itself.
• PreCheckOutcome
  The outcome of the candidate-validation’s PVF pre-check request.
• ProspectiveParachainsMessage
  Messages sent to the Prospective Parachains subsystem.
• ProvisionableData
  This data becomes intrinsics or extrinsics which should be included in a future relay chain block.
• ProvisionerMessage
  Message to the Provisioner.
• PvfCheckerMessage
  A dummy implementation to satisfy the current internal structure and cannot be constructed delibarately, since it’s not meant to be sent or used at all
• PvfExecKind
  Extends primitives::PvfExecKind, which is a runtime parameter we don’t want to change, to separate and prioritize execution jobs by request type.
• ReportPeerMessage
  Type of peer reporting
• RuntimeApiMessage
  A message to the Runtime API subsystem.
• RuntimeApiRequest
  A request to the Runtime API subsystem.
• StatementDistributionMessage
  Statement distribution message.
• StoreAvailableDataError
  The error result type of a AvailabilityStoreMessage::StoreAvailableData request.

Type Aliases
