# Futures Explained in 200 Lines of Rust
|
|
|
|
The rendered version is found at: [https://cfsamson.github.io/books-futures-explained/](https://cfsamson.github.io/books-futures-explained/)
|
|
|
|
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.
|
|
|
|
## What this book covers
|
|
|
|
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](https://github.com/stjepang) 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](https://stjepang.github.io/) to learn more
|
|
about runtimes and how they work, especially:

2. [Build your own executor](https://stjepang.github.io/2020/01/31/build-your-own-executor.html)
