Interfaces, on the other hand, are abstract types that define a method signature without implementation. A struct defines the data and methods attached to a specific object, while an interface defines a contract for behavior.
Understanding the Zero Interface Value and Its Impact on Struct Method Sets
Interestingly, you can also embed interfaces to create more complex behavioral contracts. This distinction is the bedrock of the golang interface vs struct debate.
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. This makes structs the go-to choice for managing state within an application.
H3 heading: Understanding the Zero Interface Value Struct Method Set
By programming to an interface rather than a concrete struct, you can easily swap out real implementations for mock ones during testing, which is a critical advantage for maintaining large codebases. Embedding and Composition Go favors composition over inheritance, and structs facilitate this through embedding.
