extern crate iron_rusqlite_middleware;
use iron_rusqlite_middleware::{RusqliteMiddleware, RusqliteRequestExtension};

fn handler(req: &mut Request) -> IronResult<Response> {
    // The SQLite database connection is added into the Request object through the extension
    let conn = req.database_connection();
    
    // Do your request
    
    Ok(Response::with((status::Ok, "Done."))
}

fn main() {
    // Initialize the middleware
    let rusqlite_middleware = RusqliteMiddleware::new("example.db").unwrap();
    
    // Create the Iron chain of middlewares
    let mut chain = Chain::new(handler);
    
    // Add in the middleware as before
    chain.link_before(rusqlite_middleware);
    
    // Start your Iron webserver
    let addr = "127.0.0.1:3000";
