Type Alias CommitMap

pub type CommitMap<T: Config<I>, I: 'static = ()> = StorageNMap<_GeneratedPrefixForStorageCommitMap<T, I>, (NMapKey<Blake2_128Concat, Proprietor<T>>, NMapKey<Blake2_128Concat, CommitReason<T, I>>), CommitInfo<T, I>, OptionQuery>;

Maps each Proprietor and the committed reason (CommitReason) to their commitment information.

Key Structure:

(Proprietor, CommitReason) -> CommitInfo

This storage enforces the invariant: one proprietor can have at most one commitment per reason. Each commitment is tied to a single digest, and all variant-specific details for that commitment are stored within CommitInfo.

Unlike DigestMap, which allows multiple digests per reason, CommitMap enforces at most one CommitInfo per CommitReason for each proprietor through its storage structure.

Storage type is [StorageNMap] with keys type (Proprietor < T >, CommitReason < T, I >) and value type CommitInfo < T, I >.
