Type Alias polkadot_runtime_parachains::hrmp::pallet::HrmpChannelDigests

pub type HrmpChannelDigests<T: Config> = StorageMap<_GeneratedPrefixForStorageHrmpChannelDigests<T>, Twox64Concat, Id, Vec<(BlockNumberFor<T>, Vec<Id>)>, 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 >) >.
