Return the time interval over which a leaky bucket approximates a moving-total of submitted units, as the rounded-down ratio between the specified capacity and the specified drainRate. If the rounded ratio is 0, return a time interval of 1 nanosecond. The behavior is undefined unless drainRate > 0 and capacity / drainRate can be represented with 64-bit signed integral type.
