What are some advanced examples of interfaces in Go?

Can you explain some advanced examples of interfaces in Go?

Sure! One advanced example is using interfaces for dependency injection, allowing for more flexible code.

How does dependency injection work with interfaces?

Dependency injection allows you to pass different implementations of an interface, making your code more modular.

Can you give me a code example of this?

Absolutely! Here's a simple example:

type Logger interface {
    Log(message string)
}

type ConsoleLogger struct {}

func (c ConsoleLogger) Log(message string) {
    fmt.Println(message)
}
}

func Process(logger Logger) {
    logger.Log("Processing...")
}

func main() {
    logger := ConsoleLogger{}
    Process(logger)
}

What are some other use cases for interfaces in Go?

Interfaces can be used for mocking in tests, defining behaviors for different types, and implementing polymorphism.
