Mounting middleware for the Iron web framework.

fn send_hello(req: &mut Request) -> IronResult<Response> {
    println!("Running send_hello handler, URL path: {:?}", req.url.path());
    Ok(Response::with((StatusCode::OK, "Hello!")))
}

fn intercept(req: &mut Request) -> IronResult<Response> {
    println!("Running intercept handler, URL path: {:?}", req.url.path());
    Ok(Response::with((StatusCode::OK, "Blocked!")))
}

fn main() {
    let mut mount = Mount::new();
    mount.mount("/blocked/", intercept).mount("/", send_hello);

    Iron::new(mount).http("localhost:3000");
}

Running the code above, the following HTTP requests would write the following line to the server process's stdout:

$ curl http://localhost:3000/
Running send_hello handler, URL path: [""]

$ curl http://localhost:3000/blocked/
Running intercept handler, URL path: [""]

$ curl http://localhost:3000/foo
Running send_hello handler, URL path: ["foo"]

$ curl http://localhost:3000/blocked/foo
Running intercept handler, URL path: ["foo"]

mount is a part of Iron's core bundle.

• Mount a handler on a sub-path, hiding the old path from that handler.

If you're using Cargo to manage dependencies, just add mount to the toml:

[dependencies.mount]

git = "https://github.com/iron/mount.git"

Otherwise, cargo build, and the rlib will be in your target directory.

Along with the online documentation, you can build a local copy with cargo doc.
