Functions

func Retry

func Retry(f func() error, initialBackoff, maxBackoff time.Duration, label string)

Retry retries calling a function until the function returns a non-nil error. It increments two prometheus counters to keep track of how many errors it has seen: one for all errors, and just when the max error count has been reached. The counters are indexed by the passed-in label. For best results, make sure that maxBackoff > 2*initialBackoff.
