Type Aliases

• HrmpAcceptedChannelRequestCount
  This mapping tracks how many open channel requests were accepted by a given recipient para. Invariant: HrmpOpenChannelRequests should contain the same number of items (_, X) with confirmed set to true, as the number of HrmpAcceptedChannelRequestCount for X.
• HrmpChannelContents

• HrmpChannelDigests
  Maintains a mapping that can be used to answer the question: What paras sent a message at the given block number for a given receiver. Invariants:
• HrmpChannels
  HRMP channel data associated with each para. Invariant:
• HrmpCloseChannelRequests
