description:
  This package provides a variant of a [Token Bucket](https://en.wikipedia.org/wiki/Token_bucket)
  or [Leaky Bucket](https://en.wikipedia.org/wiki/Leaky_bucket) rate-limiting algorithm optimised for low overhead.
  .
  The rate-limiting variant implemented by this package is heavily inspired by the algorithm described in
  <https://web.archive.org/web/20120808023806/http://ksdlck.com/post/17418037348/rate-limiting-at-webscale-lazy-leaky-buckets "Rate Limiting at Webscale: Lazy Leaky Buckets">.
