NewRetryPolicy(a, r, n)

with the code 

  NewRetryPolicyWithOptions(
		WithMaximumNumberAttempts(a),
		WithFixedBackoff(fb) // fb is the fixed backoff duration
		WithShouldRetryOperation(r))

  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))
