Actix

Actix – A powerful, pragmatic, and extremely fast web framework for Rust

Actix is an ecosystem of crates. The base of it is a powerful actor system for Rust on top of which the actix-web system was originally built. [...] If you are already a Rust programmer you will probably find yourself at home quickly, but even if you are coming from another programming language you should find actix-web easy to pick up.
