Async Rust

Threads are not the only way to write concurrent programs in Rust.
In this chapter we’ll explore another approach: asynchronous programming.

In particular, you’ll get an introduction to:

• The async/.await keywords, to write asynchronous code effortlessly
• The Future trait, to represent computations that may not be complete yet
• tokio, the most popular runtime for running asynchronous code
• The cooperative nature of Rust asynchronous model, and how this affects your code
