You will frequently define a struct to hold data and then define methods on that struct to give it behavior. This makes structs the go-to choice for managing state within an application.
Deciding When to Use Interface Or Struct for Abstraction
Structs: The Building Blocks of Data Structs are the workhorses of Go data modeling. Because structs are value types, they are predictable in memory layout and are ideal for representing fixed data structures.
Interfaces, on the other hand, are abstract types that define a method signature without implementation. 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.
Deciding When to Use an Interface or a Struct for Abstraction
Reader` interface only cares that a type has a `Read` method; it doesn't care if that type is a file, a network connection, or a string buffer. Embedding and Composition Go favors composition over inheritance, and structs facilitate this through embedding.
