#[main]
Expand description
Marks async main function as the Actix Web system entry-point.
Note that Actix Web also works under #[tokio::main]
since version 4.0. However, this macro is
still necessary for actor support (since actors use a System
). Read more in the
actix_web::rt
module docs.
§Examples
#[actix_web::main]
async fn main() {
async { println!("Hello world"); }.await
}
