Type Definition polkadot_runtime_parachains::hrmp::pallet::HrmpChannelDigests

pub type HrmpChannelDigests<T: Config> = StorageMap<_GeneratedPrefixForStorageHrmpChannelDigests<T>, Twox64Concat, ParaId, Vec<(BlockNumberFor<T>, Vec<ParaId>)>, ValueQuery>;

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:

• The inner Vec<ParaId> is never empty.
• The inner Vec<ParaId> cannot store two same ParaId.
• The outer vector is sorted ascending by block number and cannot store two items with the same block number.

Storage type is StorageMap with key type ParaId and value type Vec < (BlockNumberFor < T >, Vec < ParaId >) >.
