Rust 如何在actix web中执行异步函数？
有一个Rust 如何在actix web中执行异步函数？,rust,rust-actix,actix-web,Rust,Rust Actix,Actix Web,有一个asyncconnect（）函数，如下所示 use actix_web::client::Client; use futures::compat::Future01CompatExt; use futures::future::{FutureExt, TryFutureExt}; pub async fn connect() { let request = Client::default().get("https://www.google.com").send(); /
asyncconnect（）use actix_web::client::Client;
use futures::compat::Future01CompatExt;
use futures::future::{FutureExt, TryFutureExt};
pub async fn connect() {
let request = Client::default().get("https://www.google.com").send();
// compat() converts a v0.1 futures::future::Future<Item = T, Error = E>
// into a std::future::Future<Output = Result<T, E>>.
let result = request.compat().await;
if let Err(e) = result {
println!("{:?}", e);
return;
}
if let Ok(response) = result {
println!("{:?}", response);
return;
}
}

# Rust’s futures ecosystem is currently split in two:
# On the one hand we have the vibrant ecosystem built around futures@0.1 with its many libraries working on stable Rust
# and on the other hand there’s std::future ecosystem with support for the ergonomic and powerful async/await language feature.
# To bridge the gap between these two worlds we have introduced a compatibility layer as part of the futures@0.3 extension to std::future.
