Actix web is a small, fast, down-to-earth, open source rust web framework.

```rust,ignore
extern crate actix;
extern crate actix_web;
use actix_web::*;

fn index(req: HttpRequest) -> String {
    format!("Hello {}!", &req.match_info()["name"])
}

fn main() {
    let sys = actix::System::new("readme");
    HttpServer::new(
        || Application::new()
            .resource("/{name}", |r| r.f(index)))
        .bind("127.0.0.1:8080").unwrap()
        .start();

    sys.run();
}
```
