From the discussion
A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
It was all going great until I read > The design also avoids problems like function coloring and plays well with Rust's ownership rules. Async is not I/O. It can be used for I/O, but it's just a way of writing pure, deterministic state machines that keeps a logical flow together instead of scattered over a bunch of…
Sweet, this is basically how I design my protocol implementations in rust as well. Way more testable, the bulk can be shared between async and blocking IO, it's a lot easier to completely ban unsafe in your dependencies (excepting std and core), etc.
Mullvad spun their own implementation off of boringtun as well (called gotatun[0]) [0] https://github.com/mullvad/gotatun
