What are some examples of struct tags in Go?

Struct tags in Go are annotations that provide metadata about struct fields. For example, you can use tags for JSON serialization.

Can you show me a code example of using struct tags?

Sure! Here's a simple example:

type User struct {
    Name  string `json:"name"`
    Email string `json:"email"`
}

In this example, the struct fields have JSON tags that specify how they should be serialized.

What other libraries use struct tags?

Struct tags are commonly used in libraries like encoding/xml, gorm for ORM, and validator for validation.

Are there any best practices for using struct tags?

Yes, it's best to keep tags consistent, use lowercase for JSON keys, and avoid using spaces or special characters.
