BorrowedRawEvent	An owned, raw view of event data.
EventNumber	Represents an event sequence number, starting at 1
NeverSnapshot	A snapshot strategy that will never recommend taking a snapshot.
RawEvent	An owned, raw view of event data.
VersionedAggregate	A structured tuple combining an aggregate and its current version.
VersionedEvent	A structured tuple combining an event number and an event.
VersionedEventWithMetadata	A structured tuple combining an event number and an event.

Before	The starting point when reading a stream of values from an [EventSource].
Precondition	A precondition that must be upheld for a command to be executed or for events to be persisted.
Since	The starting point when reading a stream of values from an [EventSource].
SnapshotRecommendation	A recommendation on whether or not a snapshot should be persisted.
Version	An aggregate version.

Aggregate	A projected state built from a series of events.
AggregateCommand	A command that can be executed against an aggregate.
AggregateEvent	An event that can be applied to an aggregate.
AggregateId	An identifier for an aggregate.
CqrsError	Represents a common trait that all errors handled by CQRS should implement.
DeserializableEvent	An event that can be deserialized from a buffer.
Event	A thing that happened.
EventSink	A sink for writing/persisting events with associated metadata.
EventSource	A source for reading/loading events.
Events	An iterable and sliceable list of events.
SerializableEvent	An event that can be serialized to a buffer.
SnapshotSink	A sink for writing/persisting snapshots of aggregates.
SnapshotSource	A source for reading/loading snapshots of aggregates.
SnapshotStrategy	A strategy determining when to recommend a snapshot be taken.

CommandError	The error produced when this command cannot be executed against an aggregate.
ProducedEvent	The event type produced by this command.
ProducedEvents	The event sequence produced by this command.
