Performance and Memory Considerations Performance is another critical factor in the golang interface vs struct discussion. Interfaces: Contracts for Behavior Interfaces shine when you need to define flexible behavior across different types.
Why Structs Outperform Interfaces in Performance-Critical Go Code
Embedding and Composition Go favors composition over inheritance, and structs facilitate this through embedding. However, the line between the embedded types and the new type remains distinct.
For instance, an `io. 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.
Why Structs Excel in Performance-Critical Go Code
Structs are generally very cheap to allocate and pass, especially when dealing with small, fixed-size data. 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.
