// FullDataStore is an interface combining most interfaces for data stores.
// This is used by mockgen(1) to generate a mocked data store used for testing
// (see https://github.com/golang/mock). The only interface excluded is
// LockerDataStore because else we would have to explicitly expect calls for
// locking in every single test which would result in more verbose code.
// Therefore it has been moved into its own type definition, the Locker.
