go-composition

Go struct embedding allows you to inherit methods and fields from base types to build specialized structures, extending existing types without direct modification. This approach provides a flexible way to compose behaviors while keeping the codebase maintainable.

Interface embedding in Go composes multiple interfaces into a single complex contract, enabling flexible polymorphism across your application. This pattern allows you to comprehensive behavioral requirements without coupling specific implementations to the contract.

The decorator pattern in Go enhances existing handlers with additional logic like logging or authentication without modifying their core implementation. This service composition technique wraps handlers to layer supplementary behaviors around the original functionality.

Yes, Go composition patterns facilitate behavioral inheritance by using struct embedding for type extension and interface embedding for flexible contracts. This allows you to combine functionalities and implement fallback scenarios effectively within your services.

Use service composition when you need to combine multiple distinct services to achieve unified functionality and handle fallback scenarios. Struct embedding is better suited for extending a single base type's fields and methods to build a specialized structure.
