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.

So it is highly recommended to use a light asynchronous web server such as Nginx as a reverse proxy server with Rustless.

The goal of the framework is to stay out of the way as much as possible and provide a super-duper-happy path to all interactions. This means that everything in Nancy is setup to have sensible defaults and conventions, instead of making you jump through hoops and go through configuration hell just to get up and running. With Nancy you can go from zero to website in a matter of minutes. Nancy is built to run anywhere and we mean it. Right from the start, Nancy was designed to not have any dependencies on existing frameworks. Built with the .NET framework client profile, Nancy can be used pretty much wherever you want to.
