Rust actix-web with maud

How to use maud in actix web as a lightweight template engine.

---

this is a working html page handler:

use actix_web::{get, web, Result};
use maud::{html, Markup};

#[get("/")]
async fn index() -> Result<Markup> {
    // Fetch some data - this might fail, therefore using `Result` as function return value
    let page_title = await fetch_title()
		    .map_err(|_| actix_web::error::ErrorInternalServerError("could not fetch categories"))?;

    // render response
    Ok(html! {
        (maud::DOCTYPE)
        html {
            head {
						    title { (page_title) }
						}
            body {
                main class="container flex-shrink-0 py-5" {
                    h1 { (page_title) }
                }
            }
        }
    })
}

and this is how you mount it as usual:

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| App::new().service(index))
        .bind(("127.0.0.1", 8080))?
        .run()
        .await
}
