Async

Asynchronous programming is a model where tasks are delegated to a runtime that executes them concurrently. It is particularly efficient for applications where many independent IO-operations are performed, e.g. web servers.

Rust provides the necessary primitives to do asynchronous programming in the language. However, Rust's standard library does not include a runtime. For these exercises, we will use the mainstream runtime called tokio.
