static
bsls::Types::Uint64
calculateCapacity(
bsls::Types::Uint64 drainRate,
bsls::TimeInterval const& timeWindow);Return the capacity of a leaky bucket as the rounded-down product of the specified drainRate by the specified timeWindow. If the result evaluates to 0, return 1. The behavior is undefined unless the product of drainRate and timeWindow can be represented by a 64-bit unsigned integral type.
capacity as the rounded-down product of drainRate by timeWindow, or 1 if that product is 0
| Name | Description |
|---|---|
| drainRate | rate at which units drain from the bucket |
| timeWindow | interval over which the capacity is calculated |
