Summary

Good job! In this chapter, we introduced quite a bit of code and set up an example that we’ll continue using in the following chapters.

So far, we’ve focused on futures and async/await to model and create tasks that can be paused and resumed at specific points. We know this is a prerequisite to having tasks that are in progress at the same time. We did this by introducing our own simplified Future trait and our own coroutine/wait syntax that’s way more limited than Rust’s futures and async/await syntax, but it’s easier to understand and get a mental idea of how this works in contrast to fibers/green threads (at least I hope so).

We have also discussed the difference between eager and lazy coroutines and how they impact how you achieve concurrency. We took inspiration from Tokio’s join_all function and implemented our own version of it.

In this chapter, we simply created tasks that could be paused and resumed. There are no event...
