I finished the 4th and final part to my "how I understood async/await in Rust" series of blog posts: https://hegdenu.net/posts/understanding-async-await-4/

In this one we look at doing something that can't be done without writing a "manual" future implementation. Namely writing an async channel.

Yesterday I published part 3 of my series on "how I finally understood async/await in #Rust".

The topic is "why shouldn’t I hold a mutex guard across an await point?".

There is another great post related to understanding async/await in #rust in @thisweekinrust 503.

How to think about `async`/`await` in Rust by @cliffle:

I understand that it's not new so much as newly extraced from existing documentation. In any event, it's a great read if you're trying to wrap your head around async/await.

This post on Pin in #async #rust is fantastic!

If you’ve ever struggled to understand what Pin is trying to do and how it relates to all that Unpin and !Unpin stuff, have a read!

Found via @thisweekinrust 503.

I recently heard about someone using #tokioConsole from a “custom runtime” (not using the `tokio_unstable` flag). I’m not sure if they meant custom #tokio or a non-tokio custom runtime.

Honestly, either of those happening is pretty cool. I’d love to hear from anyone else doing anything similar too!

I've finished part 2 of my series on "how I finally understood async/await in #Rust".

The topic is "how does a pending future get woken?".

@KevinWho @soulsource The Rust Foundation does maintain a library with the ability to execute asynchronous functions (https://crates.io/crates/futures), but they made the intentional decision to not include it in the standard library.

(I'd still recommend #tokio (https://crates.io/crates/tokio) as the go-to #AsyncRust runtime, though!)
