Go Visitor Pattern to pass and apply options

Go Visitor Pattern

type Logger struct {
	Prop1 string
	Prop2 string
}

type Option func(l *Logger) error

func Prop1Option() Option {
	return func(l *Logger) error {
		l.Prop1 = "hello"
		return nil
	}
}

func Prop2Option(w string) Option {
	return func(l *Logger) error {
		l.Prop1 = w
		return nil
	}
}

func (l *Logger) SetOptions(opts ...Option) error {
	for _, applyOptTo := range opts {
		if err := applyOptTo(l); err != nil {
			return err
		}
	}
	return nil
}

func testing()  {
	l := new(Logger)
	err := l.SetOptions(Prop1Option(), Prop2Option("world"))
	log.Error(err)
}
