    let config = depot.obtain::<Config>().unwrap();
    let custom_data = depot.get::<&str>("custom_data").unwrap();
    format!("Hello World\nConfig: {:#?}\nCustom Data: {}", config, custom_data)
}

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt().init();

    tracing::info!("Listening on http://127.0.0.1:7878");
    Server::new(TcpListener::bind("127.0.0.1:7878")).serve(route()).await;
