SnapshotTailReaders

class SnapshotTailReaders @InternalWowApi constructor(default: SnapshotTailReader?, placed: Map<AggregateType, SnapshotTailReader?> = emptyMap())

The one-round-trip reads of a context's snapshots with their tails (Store.snapshotTails): the default one, of the aggregate types the layout places nowhere in particular, when their log store holds their primary snapshots, and the one of each type placed elsewhere, null when its log and primary snapshots are on different stores.
