This book aims to explain Futures in Rust using an example driven approach,
exploring why they're designed the way they are, and how they work. We'll also
take a look at some of the alternatives we have when dealing with concurrency
in programming.
Going into the level of detail I do in this book is not needed to use futures or async/await in Rust. It's for the curious out there that want to know how it all works.
This book will try to explain everything you might wonder about up until the topic of different types of executors and runtimes. We'll just implement a very simple runtime in this book introducing some concepts but it's enough to get started.
Stjepan Glavina has made an excellent series of articles about async runtimes and executors, and if the rumors are right there is more to come from him in the near future.
The way you should go about it is to read this book first, then continue reading the articles from stejpang to learn more about runtimes and how they work, especially:
