An example of an AI chatbot conversation about error handling in Go interfaces.
How do I handle errors in Go interfaces?
In Go, you can handle errors in interfaces by defining methods that return an error type. Can you provide an example?
Sure! I have an interface for a database operation. How should I implement error handling?
You can define your interface method to return an error. For example, func (db *Database) Query(query string) (Result, error).
What if the error is not related to the interface but to the implementation?
In that case, the implementation should still return an error. You can wrap the error with additional context using fmt.Errorf.
