在actix-web中处理异步处理程序中的错误最常用的方法是什么？

use actix_web::{Error, get, web, App, HttpResponse, HttpServer};
use std::io;

#[get("/")]
async fn index() -> Result<HttpResponse, Error> {
    let result: Result<String, io::Error> = Err(io::Error::new(io::ErrorKind::Other, "Something went wrong"));
    let response = result.map(|data| HttpResponse::Ok().body(data)).map_err(Error::from)?;
    Ok(response)
}

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