• Rewriting Rust

  I agree wholeheartedly (and I'm not surprised that you of all people often write raw futures!). I want to push back on the "async rust bad/failure/not ready" meme because

  - it's perfectly possible to be a successful user of the async ecosystem as it is now while building great software;

  - this two-tiered phenomenon is not unique to Rust, JS and Python struggle with it just as much (if not more due to less refined and messier design). As an example, [1] is elegant, but complex, and I'm less sure it's correct compared to a gnarly async Rust future, because the underlying async semantics are in flux.

  Of course I'd love for the remaining snags (like AFIT) to go away, and simplified Pin story or better APIs would be great, but this negativity around async Rust is just wrong. It's a massive success already and should be celebrated.

  I recommend anyone interested in this topic to take a look at aiometer.
