How does inheritance work with structs in Go?

How does inheritance work with structs in Go?

In Go, structs do not support inheritance like in traditional OOP languages. Instead, Go uses composition. You can embed one struct within another to achieve similar behavior.

Can you give me an example of struct embedding?

Sure! Here's a simple example:

type Animal struct {
    Name string
}

type Dog struct {
    Animal  // Embedding Animal struct
    Breed string
}

func main() {
    myDog := Dog{Animal: Animal{Name: "Buddy"}, Breed: "Golden Retriever"}
    fmt.Println(myDog.Name)  // Accessing embedded struct field
}

What are the benefits of using composition over inheritance?

Composition allows for more flexible code reuse and avoids the complexities of inheritance hierarchies. It promotes better encapsulation and makes it easier to change implementations.

Are there any limitations to using structs in Go?

Yes, one limitation is that you cannot inherit methods directly from a struct. You need to define methods for each struct explicitly, which can lead to code duplication if not managed properly.
