It does not require explicit implements, and as long as a struct implements all the functions in interface, the compiler automatically thinks it implements this interface. The first time I saw this design, my first reaction was: What's the fuck? What is the difference between the design of this wonderful flower and the explicit implement or inhe

The mainstream development language, in order to achieve low coupling between projects, will be implemented by the IOC framework. Abstraction and implementation separation, using the abstraction layer, do not care about the concrete implementation of these layers of abstraction, the implementation of the abstraction layer can be implemented independently. Now the more popular domain-driven design (DDD), in order to achieve the domain layer as the most core, also needs to rely on the IOC.Looking
