Asynchronous Programming in Rust

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 ...
