sans-IO implementation of iroh?

[thkoch2001]

I'm new to rust but very much try to avoid async.

There are people that believe that you can remain neutral in regards to async or no-async and that this even comes with advantages in testabilty:
sans-IO: The secret to effective Rust for network services.

I've read Async Rust Challenges in Iroh.

There is quinn-proto which could help to also make iroh sans-IO.

What is your take on this?

Sans-io is great, and we try to follow it when we can.

There's no sans-io implementation of all of iroh at this point, and I think trying to make iroh one would be a bigger undertaking.
We've played with the idea to allow running iroh fully deterministically and fuzz-test a bunch of pieces of the stack in one go. That said, it'd likely still involve async code, and we don't have concrete plans to do this right now.
