The Google Cloud Go library contains the following code (See
https://github.com/googleapis/google-cloud-go/blob/38a040e213cc8af5b01b3afe422481493f54382f/datastore/client.go#L36
)
// datastoreClient is a wrapper for the pb.DatastoreClient
type datastoreClient struct {
// Embed so we still implement the DatastoreClient interface,
// if the interface adds more methods.
pb.DatastoreClient
c pb.DatastoreClient
}
func newDatastoreClient() pb.DatastoreClient {
return &datastoreClient{ c: pb.NewDatastoreClient() }
}
func (dc *datastoreClient) Lookup() {
// ...
What could be the reason for both an anonymous and a named structure
implementation, without initializing the anonymous one? As I understand it,
this means the compiler no longer complains about missing methods from the
`pb.DatastoreClient` interface, but it would crash with a nil pointer error
when they are called?
thanks,
Remko
