Module ructe::Using_static_files::c_Iron

How to serve static files with the Iron web framework.

Somewhere (maybe in main), you probably create a router. To add a static handler could look something like this:

// Somewhere (maybe in main) you create a router
let mut router = Router::new();
// Among the routes, you add this:
router.get("/static/:name", static_file, "static_file");
// Go on to start an Iron server with the router

Then the actual handler needs to be implemented. Here’s one implementation.

fn static_file(req: &mut Request) -> IronResult<Response> {
    // Extract the requested file name from the router
    let router = req.extensions.get::<Router>().expect("router");
    let name = router.find("name").expect("name");
    // If the static files exists, serve it
    if let Some(data) = statics::StaticFile::get(name) {
        Ok(Response::with((status::Ok, data.mime(), data.content)))
    } else {
        debug!("Static file {} not found", name);
        Ok(Response::with((
            status::NotFound,
            mime!(Text / Plain),
            "not found",
        )))
    }
}

This implementation uses the mime02 feature of ructe. Relevant parts of Cargo.toml might look like this:

[build-dependencies]
ructe = { version = "^0.3.2", features = ["sass", "mime02"] }

[dependencies]
iron = "^0.5.1"
router = "^0.5.1"
mime = "0.2.6"

There is a full example as examples/iron in the ructe repository.
