Parameters
| Name | Description |
|---|---|
| tokensPerSecond | the rate at which new tokens are deposited at the bucket. Actual rate might vary slightly due to rounding errors. In general, the lower the number, the lower the error. |
| burstSize | the maximal number of tokens that the bucket may hold. Unless overdraft is allowed, this is also the maximal amount that a single withdrawl may request. |
| numInitialTokens | the number of tokens initially in the bucket. If unspecified, the bucket starts out as completely full. |
