Rustless

Rustless is a REST-like API micro-framework for Rust. It's designed to provide a simple DSL to easily develop RESTful APIs on top of the Iron web framework. It has built-in support for common conventions, including multiple formats, subdomain/prefix restriction, content negotiation, versioning, and much more. Rustless in a port of Grape library from Ruby world. Based on hyper, an HTTP library for Rust. Like Rust itself, Rustless is still in the early stages of development, so don't be surprised if APIs change and things break. If something's not working properly, file an issue or submit a pull request! Rustless is based on Iron, which is based on Hyper, which is synchronous. Hyper has a lot of limitations right now, and can't handle many simultaneous connections, especially with keep-alive. So it is highly recommended to use a light asynchronous web server such as Nginx as a reverse proxy server with Rustless.
