go-structs-interfaces

Design small Go interfaces by defining them at the consumer side and composing them for flexible boundaries. This approach ensures testable dependencies and idiomatic type relationships across your service layer.

Choose pointer receivers when modifying struct state or handling large structs, and value receivers for read-only or small immutable data. Correct receiver choices ensure idiomatic Go abstraction patterns and prevent mutation bugs.

Apply composition and embedding patterns in Go by embedding structs to reuse fields and promote methods. This technique builds maintainable type relationships and clear dependency boundaries without complex inheritance.

Structure serialization-friendly Go structs by adding field tags for JSON or database mapping and applying compile-time checks. This ensures correct data serialization and validates interface implementations at build time.

Yes, you can review existing Go types for API design by evaluating interface placement and dependency boundaries. This process identifies confusing abstractions and suggests idiomatic struct designs for maintainable codebases.
