Variables

var RetryClosure = func() func() {
	retryIn := 0
	fibonacci := Fibonacci()
	return func() {
		if retryIn > 0 {
			durationString := fmt.Sprintf("%vs", retryIn)
			duration, _ := time.ParseDuration(durationString)

			log.Printf("Retrying in %v seconds", retryIn)
			time.Sleep(duration)
		}
		retryIn = fibonacci()
	}
}

A useful closure we can use when there is a problem connecting to the broker It uses Fibonacci sequence to space out retry attempts

Functions

func Fibonacci

func Fibonacci() func() int

Fibonacci returns successive Fibonacci numbers starting from 1

func ReflectValue

func ReflectValue(theType string, value interface{}) (reflect.Value, error)

ReflectValue converts interface{} to reflect.Value based on string type
