Structs

• CommittedCandidateReceipt
  A candidate-receipt with commitments directly included.
• CoreIndex
  The unique (during session) index of a core.
• InboundDownwardMessage
  A wrapped version of DownwardMessage. The difference is that it has attached the block number when the message was sent.
• InboundHrmpMessage
  An HRMP message seen from the perspective of a recipient.
• OverseerHandle
  A handle used to communicate with the Overseer.
• ParaId
  Unique identifier of a parachain.
• PersistedValidationData
  The validation data provides information about how to create the inputs for validation of a candidate. This information is derived from the chain state and will vary from para to para, although some fields may be the same for every para.
• ValidationCodeHash
  Unit type wrapper around Hash that represents the blake2-256 hash of validation code in particular.

Enums

• CoreState
  The state of a particular availability core.
• OccupiedCoreAssumption
  An assumption being made about the state of an occupied core.
• RelayChainError

Traits

• RelayChainInterface
  Trait that provides all necessary methods for interaction between collator and relay chain.

Functions

• call_runtime_api
  Helper function to call an arbitrary runtime API using a RelayChainInterface client. Unlike the trait method, this function can be generic, so it handles the encoding of input and output params.

Type Aliases

• BlockNumber
  The block number type used by Polkadot. 32-bits will allow for 136 years of blocks assuming 1 block per second.
• PHash
  A hash of some data used by the relay chain.
• PHeader
  Header type.
• RelayChainResult
• SessionIndex
  Simple index type with which we can count sessions.
• StorageValue
  Storage value.
• ValidatorId
  Identity that parachain validators use when signing validation messages.
