Rush: Throttling Algorithms

Rush is a Python library that provides a composable and extensible framework for implementing various rate limiting algorithms and storage backends. It includes a periodic interval rate limiter, a leaky bucket rate limiter (Generic Cell Ratelimiting Algorithm - GCRA), and supports Redis and in-memory dictionary storage. The library emphasizes type annotations and requires Python 3.6 or newer. The current version is 2021.4.0, released in April 2021.
