Nom's official documentation includes trivially simple examples (e.g. how to parse a hexadecimal RGB color code) and very complicated examples (e.g. how to parse json). When I first learned nom I found a steep learning curve in between the simple and complex examples. Furthermore, previous versions of nom, and most of the existing documentation, use macros. From nom 5.0 onward macros are soft-deprecated in favor of functions. This tutorial aims to fill the gap between simple and complex parsers by parsing the contents of /proc/mounts, and it demonstrates the use of functions instead of macros.

In the previous lesson in the crash course, we covered the new async/.await syntax stabilized in Rust 1.39, and the Future trait which lives underneath it. This information greatly supercedes the now-defunct lesson 7 from last year, which covered the older Future approach.

Now it’s time to update the second half of lesson 7, and teach the hot-off-the-presses Tokio 0.2 release.

In which we explore Rust's newly stabilized async/.await language feature by creating a simple, asynchronous application. We look at what you need to do asynchronous programming in Rust and how it differs from other languages. And we talk a little bit about Pokémon!

This book is targeted towards experienced programmers that already feel somewhat comfortable with vanilla Rust (you definitely do not need to be an "expert" though, I certainly am not) and would like to dip their toes into its async ecosystem.

As the title indicates, this is not so much a book about how to use async Rust as much as it is about trying to build a solid understanding of how it all works under the hood. From there, efficient usage should come naturally.
