I freely admit I’m frustrated by the discourse around async Rust! I’m also very frustrated because I feel I was iced out of the project for petty reasons to do with whom I’m friends with and the people who were supposed to take over my work have done a very poor job, hence the failure to ship much of value to users. What we shipped in 2019 was an MVP that was intended to be followed by several improvements in quick succession, which the Rust project is only now moving toward delivering. I’ve written about this extensively.

My opinion is that async Rust is an incredible achievement, primarily not mine (among the people who deserve more credit than me are Alex Crichton, Carl Lerche, and Aaron Turon). My only really significant contributions were making it safe to use references in an async function and documenting how to interface with completion based APIs like io-uring correctly. So it is very frustrating to see the discourse focused on inaccurate statements about async Rust which I believe is the best system for async IO in any language and which just needs to be finished.
