NewRetryPolicyWithOptions( WithMaximumNumberAttempts(a), WithFixedBackoff(fb) // fb is the fixed backoff duration WithShouldRetryOperation(r))
or
NewRetryPolicyWithOptions( WithMaximumNumberAttempts(a), WithExponentialBackoff(mb, e) // mb is the maximum backoff duration, and e is the base for exponential backoff, e.g. 2.0 WithShouldRetryOperation(r))

func WithFixedBackoff ¶
func WithFixedBackoff(newSleepBetween time.Duration) RetryPolicyOption
WithFixedBackoff is an option for NewRetryPolicyWithOptions that sets the backoff to always be exactly the same value. There is no jitter either. Therefore, WithFixedBackoff is a combination of WithNextDuration, withMinSleepBetween, withMaxSleepBetween, and withExponentialBackoffBase.
