warp
A super-easy, composable, web server framework for warp speeds
The fundamental building block of warp is the Filter, they can be combined and composed to express rich requirements on requests. A Filter in warp is essentially a function that can operate on some input, either something from a request, or something from a previous Filter, and returns some output, which could be some app-specific type you wish to pass around, or can be some reply to send back as an HTTP response.
