Practical Usage and Design Patterns In practice, the choice between an interface and a struct often dictates the architecture of your codebase. 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.
Memory Layout of Interface Versus Struct in Go
Because structs are value types, they are predictable in memory layout and are ideal for representing fixed data structures. Interfaces: Contracts for Behavior Interfaces shine when you need to define flexible behavior across different types.
Embedding and Composition Go favors composition over inheritance, and structs facilitate this through embedding. This makes structs the go-to choice for managing state within an application.
Understanding Memory Layout Differences Between Interface and Struct in Go
Interestingly, you can also embed interfaces to create more complex behavioral contracts. 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.
