I think a lot of people inadvertently assume async #RustLang is so different from sync Rust, because the way it is - when in fact it's because of the (most popular) async runtime they're using.

We should look way more into alternative #async runtimes to #Tokio, e.g. smol:

https://floss.social/@janriemer/111669258656959538

#Smol allows you to use non-'static Futures by using a local executor:

It looks a lot more like "normal" #Rust.

Beul - it executes futures | by Bert Peters

https://lib.rs/crates/beul

"Beul is a minimalistic futures executor. No dependencies, no unsafe #Rust. It simply executes futures."

It can't get any simpler than that. ¯\_(ツ)_/¯

This thing will (probably) blow up 🚀

mfio - Framework for #Async I/O Systems:

https://github.com/memflow/mfio

"mfio is a one-stop shop for custom async I/O systems. It allows you to go wild, beyond typical OS APIs.[...]"

- Async
- Automatic batching (vectoring)
- Fragmentation
- Partial success
- Lack of color (full sync support)
- I/O directly to the stack
- Using without standard library

@matze Yes, that's true.

However, writing the desugared version in the trait is still compatible with using async fn in the _trait impl_, so the "burden" is more on lib maintainers.

Also this problem only applies when the Self type is generic.

And `Send` is only required, if one decides to use a multithreaded rt.

I highly recommend the following article by @notgull about smol:

Why you might actually want async in your project

Why you might actually want async in your project

There is a common sentiment I’ve seen over and over in the Rust community that I think is ignorant at best and harmful at worst.

*makes some happy screaming noise*

#Rust will end this year with a long awaited feature that will define it's future:

We will get "async fn and return-position impl Trait in trait" (#AFIT & #RPITIT).

It will be stabilized in the next #RustLang version 1.75, which will be released on 28 December, 2023.

@notgull This is such a good blog post. I've learned a lot!

Thank you for sharing. ❤️

"The best part is that the allocation, the Vec<smol::Task<()>>, isn’t even necessary. It could be one-time allocation that is just extended to hold the tasks."

Wow, this is mind-blowing to me - I haven't even considered this before! 🤯

Memory-reuse FTW!
