Module polkadot_node_subsystem_util::inclusion_emulator

An emulator for node-side code to predict the results of on-chain parachain inclusion and predict future constraints.

Structs

• ConstraintModifications
  Modifications to constraints as a result of prospective candidates.
• Constraints
  Constraints on the actions that can be taken by a new parachain block. These limitations are implicitly associated with some particular parachain, which should be apparent from usage.
• Fragment
  A parachain fragment, representing another prospective parachain block.
• InboundHrmpLimitations
  Constraints on inbound HRMP channels.
• OutboundHrmpChannelLimitations
  Constraints on outbound HRMP channels.
• OutboundHrmpChannelModification
  An update to outbound HRMP channels.
• ProspectiveCandidate
  The prospective candidate.
• RelayChainBlockInfo
  Information about a relay-chain block.

Enums

• FragmentValidityError
  Kinds of errors with the validity of a fragment.
• HrmpWatermarkUpdate
  An update to the HRMP Watermark.
• ModificationError
  Kinds of errors that can occur when modifying constraints.

Traits

• HypotheticalOrConcreteCandidate
  Trait for a hypothetical or concrete candidate, as needed when assessing the validity of a potential candidate.
