Summary

So, in this chapter, we did two things. First, we made some rather minor changes to our runtime so it works as an actual runtime for Rust futures. We tested the runtime using two external HTTP client libraries to learn a thing or two about reactors, runtimes, and async libraries in Rust.

The next thing we did was to discuss some of the things that make asynchronous Rust difficult for many programmers coming from other languages. In the end, we also talked about what to expect going forward.

Depending on how you’ve followed along and how much you’ve experimented with the examples we created along the way, it’s up to you what project to take on yourself if you want to learn more.

There is an important aspect of learning that only happens when you experiment on your own. Pick everything apart, see what breaks, and how to fix it. Improve the simple runtime we created to learn new stuff.

There are enough interesting projects to pick from, but here...
