What are embeddings in Golang and how can I use them?

Embeddings in Golang refer to a way of including one struct type within another, allowing for code reuse and composition.

Can you give me an example of how to implement embeddings in a Golang struct?

Sure! Here's a simple example:

type Address struct {
    City  string
    State string
}

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

In this example, the Person struct embeds the Address struct.

What are the benefits of using embeddings in my code?

Using embeddings promotes code reuse, reduces redundancy, and makes your code more organized and easier to maintain.

Are there any performance considerations I should be aware of?

Generally, embeddings do not have significant performance overhead, but it's essential to manage memory usage and struct sizes carefully.
