This is the essence of dependency injection in Go. Understanding how embedding interacts with the golang interface vs struct paradigm allows developers to build highly modular systems without the complexity of traditional class hierarchies.
Golang Best Practices: Choosing the Right Interface or Struct</answer_end}
You will frequently define a struct to hold data and then define methods on that struct to give it behavior. This decouples your code from specific implementations, making it easier to test and extend.
Interfaces introduce a level of indirection because they hold a dynamic type; this involves a pointer to the underlying data and a pointer to the type information. Therefore, performance-critical code often prefers concrete types to avoid the allocation and garbage collection pressure associated with interface usage.

It is a blueprint for creating specific, tangible instances of data. This composition model encourages small, focused types that can be assembled into larger structures.
