How to do it...

In a few steps, we'll be able to use async and await in Rust for seamless concurrency:

1. Create a new binary application using cargo new async-await and open the directory in Visual Studio Code.
2. As usual, when we are integrating a library, we'll have to add the dependencies to Cargo.toml:

[package]name = "async-await"version = "0.1.0"authors = ["Claus Matzinger <[e-mail]>"]edition = "2018"[dependencies]runtime = "0.3.0-alpha.6"surf = "1.0"

3. In src/main.rs, we have to import the dependencies. Add the following lines at the top of the file:

use surf::Exception;use surf::http::StatusCode;

4. The classic example is waiting for a web request to finish. This is notoriously difficult to judge since the web resources ...
