Struct embedding is an unnamed field that incorporates another type into a Go struct. The containing type can use the embedded type’s methods and fields, giving composition an inheritance-like feel without an inheritance system. section 1.2.1 section 10.2.2
Embedding a generated gRPC server
A gRPC server embeds the generated implementation to satisfy a required interface method while adding its own dependencies and endpoints: ```go type Server struct { api.UnimplementedHabitsServer lgr Logger } func (s *Server) CreateHabit( _ context.Context, request *api.CreateHabitRequest, ) (*api.CreateHabitResponse, error) { s.lgr.Logf("CreateHabit request received: %s", request) return &api.CreateHabitResponse{ Habit: &api.Habit{}, }, nil } ``` The embedded `UnimplementedHabitsServer` supplies the required `mustEmbedUnimplementedHabitsServer` method, allowing `Server` to register as a `HabitsServer`. section 10.2.2
// Server is the implementation of the gRPC server.
type Server struct {
api.UnimplementedHabitsServer
lgr Logger
}
Inspect the compact server definition that combines an embedded generated service with a named logger field. section 10.2.2
