Fantastic article! I've been experimenting with Rust async/await and it cuts down so much boilerplate in handling futures.

Totally agree, John. I also love the ergonomics. I think async/await will finally make Rust's concurrency model accessible to a larger audience.

While I agree that async/await simplifies the syntax, I don't think it makes Rust's concurrency more accessible. I found Rust's message passing to be more intuitive and less error-prone.

I've used message passing too, and it certainly has its uses. However, async/await is easier to grok for developers already familiar with Promises in JS. Plus, there's less cognitive overhead when dealing with both concurrency and synchronous tasks.

Async/await definitely simplifies asynchronous programming. But, are there any limitations we should be aware of or any potential pitfalls?

Great question! Yes, there are scenarios async/await doesn't handle well, like CPU-bound tasks. Also, error handling can be tricky for beginners. Check this related Reddit thread: https://www.reddit.com/r/rust/comments/j78901/pitfalls_of_asyncawait/

I think both message passing and async/await have their roles. The Tokio team is working on integrating both patterns seamlessly in the ecosystem. Exciting times ahead!

Definitely! I'm looking forward to seeing how the ecosystem evolves and what the best practices emerge.

For those looking for detailed tutorials, I suggest checking out the Rust async book. It covers async/await in-depth and even dives into advanced topics like stream handling and synchronization: https://rust-lang.github.io/async-book/

The async book is a fantastic resource. I also recommend checking out the Tokio project itself if you want to see async/await in action: https://tokio.rs/
