QueryBindings

@WowSpi
fun interface QueryBindings<in K : Any>

What a storage serves for each K: the QueryBackendBinding of each aggregate type's snapshots or events (QueryBindings<AggregateType>), or of each dataset (QueryBindings<QueryDataset>), null for a key it does not serve. A dataset whose storage binding it cannot read fails with an IllegalArgumentException: that is a misconfiguration, not a key it does not serve.
