What are some use cases for struct embedding in Go?

Struct embedding in Go allows for code reuse and composition. Common use cases include creating complex data structures, implementing interfaces, and enhancing functionality without inheritance.

Can you give me an example of struct embedding in a real-world application?

Sure! For instance, in a web application, you might embed a struct for user authentication within a struct for user profiles, allowing you to manage user data and authentication methods together.

What are the advantages of using struct embedding over traditional inheritance?

Struct embedding promotes composition over inheritance, leading to more flexible and maintainable code. It avoids the complexities of inheritance hierarchies and allows for easier code reuse.

Are there any downsides to using struct embedding?

One downside is that it can lead to larger structs if not managed properly, and it may introduce ambiguity if multiple embedded structs have methods with the same name.
