Reinventing Asynchronous Rust

A Brief Intro To Asynchronous Programming In Rust

Lets say you want to write some async/.await code in Rust, since it's new and cool. Let's start with the simplest async program that you could write (a timer). First we have to create a Future, something that completes at some point in the future but won't start unless you execute it (in Rust, this is called lazy evaluation). Here's some code to start:
