Overview of this book

Step into the world of asynchronous programming with confidence by conquering the challenges of unclear concepts with this hands-on guide. Using functional examples, this book simplifies the trickiest concepts, exploring goroutines, fibers, futures, and callbacks to help you navigate the vast Rust async ecosystem with ease. You’ll start by building a solid foundation in asynchronous programming and explore diverse strategies for modeling program flow. The book then guides you through concepts like epoll, coroutines, green threads, and callbacks using practical examples. The final section focuses on Rust, examining futures, generators, and the reactor-executor pattern. You’ll apply your knowledge to create your own runtime, solidifying expertise in this dynamic domain. Throughout the book, you’ll not only gain proficiency in Rust's async features but also see how Rust models asynchronous program flow. By the end of the book, you'll possess the knowledge and practical skills needed to actively contribute to the Rust async ecosystem.

Creating Your Own Runtime

In the last few chapters, we covered a lot of aspects that are relevant to asynchronous programming in Rust, but we did that by implementing alternative and simpler abstractions than what we have in Rust today.

This last chapter will focus on bridging that gap by changing our runtime so that it works with Rust futures and async/await instead of our own futures and coroutine/wait. Since we’ve pretty much covered everything there is to know about coroutines, state machines, futures, wakers, runtimes, and pinning, adapting what we have now will be a relatively easy task.

When we get everything working, we’ll do some experiments with our runtime to showcase and discuss some of the aspects that make asynchronous Rust somewhat difficult for newcomers today.

We’ll also take some time to discuss what we might expect in the future with asynchronous Rust before we summarize what we’ve done and learned in this book.

We’ll...
