There are a lot of guides about how to use async Rust from a "user's perspective", but I think it's also worth understanding how it works, what those async blocks actually mean. Why you get all those weird pinning errors.
Async: What is blocking? – Alice Ryhl
The async/await feature in Rust is implemented using a mechanism known as cooperative scheduling, and this has some important consequences for people who write asynchronous Rust code.
Exploring ways to make async Rust easier
Asynchronous Rust is powerful but has a reputation for being hard to learn. There have been various ideas on how to fix the trickiest aspects, though with my focus being on Tokio 1.0, I had not been able to dedicate much focus to those topics. However, Niko’s async vision effort has recently started the discussion again, so I thought I would take some time to participate. In this article, I collect some previously proposed ideas and offer some new ones, tying them together to explore what could be.
397 - Challenges with async/await in the control plane | RFD | Oxide
Very early in the development of the control plane, we considered whether to build our big new distributed system using Rust’s async/await or more traditional synchronous threaded code. [RFD 79] discussed this issue and came to the weak conclusion to prefer async/await, in no small part because much of the ecosystem we wanted to use (e.g., low-level http crates) was already async and seemed to be moving further in that direction, and we’d already written some async code.

Building a mental model for async programs
In my experience writing async programs in Dart and Rust, I have built up a model in my head to avoid bugs caused by async. These bugs are usually hard to find and reproduce, so there is a lot of value in taking preventive measures to avoid them. I hope to improve this model in my head by writing this post and to share them with anyone who might find it helpful.
400 - Dealing with cancel safety in async Rust | RFD | Oxide
While developing the control plane, we’ve found that one of the bigger practical issues has been async cancel correctness: the relatively unpredictable way an async Rust system can behave if futures are dropped [rfd397]. Cancellation is an example of "spooky action at a distance", and having to think about it imposes a significant cognitive burden on authors and reviewers of asynchronous code. Both of these are quite uncharacteristic of Rust.
async/await: It’s Good and Bad
This might be controversial, as most people I know are huge fans of async/await. If you’re not familiar, it’s this nifty little syntax…
