Let us part ways, then, and in the meantime I encourage you to find the light you must be missing in your life.
To clarify what you seem not to understand: the code in the blog post depends on a library called monoio, and based on the post's description of the behavior of that code (I haven't actually read the source for monoio), monoio contains a bug. I don't dispute that this code behaves incorrectly, just that it has anything to do with Rust's facility for async IO rather than with the specific IO library employed in the post.

Could you please not post like this to Hacker News? It's not what this site is for, and destroys what it is for. (https://news.ycombinator.com/item?id=41996506 was much better, of course.)
