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. For instance, an `io.
Polymorphism Without Inheritance: Structs Embracing Interfaces
However, the line between the embedded types and the new type remains distinct. This is the essence of dependency injection in Go.
Defining the Core Concepts A struct in Go is a concrete data type that groups together variables under a single name, known as fields. Instead of specifying *what* something is, an interface specifies *what it can do*.
Polymorphism Without Inheritance: How Go Structs Can Satisfy Interfaces
Interestingly, you can also embed interfaces to create more complex behavioral contracts. If you want other parts of your code to interact with that behavior without knowing the specifics, you define an interface that the struct satisfies.
