What are the differences between interfaces and structs in Go?

What are the differences between interfaces and structs in Go?

In Go, structs are used to define data structures, while interfaces define a set of methods that a type must implement.

Can you give me an example of when to use an interface instead of a struct?

Sure! Use an interface when you want to define behavior that can be shared across different types, like a 'Reader' interface.

How do I implement an interface in a struct?

To implement an interface, just define the methods specified by the interface in your struct. Go does this implicitly.

What are some common use cases for interfaces in Go?

Common use cases include defining behaviors for different types, dependency injection, and writing more flexible code.
