The promise of Async Rust often clashes with its current reality. This article argues that despite its potential, Async Rust remains in an MVP state, creating a 'two-tiered ecosystem' for developers. It highlights how Tokio's monoculture and the `Send + 'static` trap introduce significant complexity and overhead, often making traditional threading a more ergonomic and performant choice for common…

Async Rust never left the MVP state

Tokio!
It's 'static + multithreaded-by-default requirement has created the myth that async #Rust is inherently difficult.
People should use `smol` more - here's why:

The Evolution of Async Rust: From Tokio to High-Level Applications
#RustLang #Rustrover #Asyncrust #Rust #Tokio
Tokio has become the de facto asynchronous runtime for high-performance networking in Rust, powering everything from backend services to databases. During the discussion, they explored how async Rust matured over the years, the architectural decisions behind Tokio, common challenges developers face today, and where the ecosystem is heading next.
Ok, @calisti, I _think_, I've figured it out now (please read until the later parts of the toots as they are the most important)!🤓
Tldr; The `or` or `race` operators _on their own_ are not suitable for cancelling streams! One needs a `StopToken` or enum value _within the stream_ that signals cancellation/allows for short-circuiting.

Hey #Rust,
how dare you look so elegant as a systems programming language! 💅
Second: Pinning helpers!
When doing async #Rust, there will be a point, where you'll get the ominous "Doesn't implement Unpin" error and "You need to pin your value".
First, learn about Pinning:
https://doc.rust-lang.org/std/pin/
Like, _really_ learn and understand it:
https://fasterthanli.me/articles/pin-and-suffering
And then use smol's pin! macro and the `pin_project` crate:
https://docs.rs/pin-project/latest/pin_project/
I might continue this thread with more insights I gain during this little project - stay tuned! 🙂
