What are some examples of struct embedding in Go?

Can you explain struct embedding in Go with some examples?

Sure! Struct embedding in Go allows one struct to include another struct as a field, promoting code reuse. For example:

type Address struct {
    City  string
    State string
}

type Person struct {
    Name    string
    Age     int
    Address // Embedded struct
}

In this example, Person has an embedded Address struct.

What are the benefits of using struct embedding?

The benefits include code reuse, better organization, and the ability to access fields of the embedded struct directly. For instance, you can access City directly from a Person instance.

Can you show me how to create a new Person and access the embedded Address fields?

Absolutely! Here's how you can create a new Person and access the Address fields:

p := Person{Name: "John", Age: 30, Address: Address{City: "New York", State: "NY"}}
fmt.Println(p.Name)       // Output: John
fmt.Println(p.Address.City) // Output: New York
