This is a bit corollary to the article so my apologies for that. What I find most unproductive in Rust is the idioms that don't find their place in the official docs. Steve Klabnik wrote an excellent comment here in HN 4-5 months ago about how to use a thread pool which illustrated my gripes with Rust PERFECTLY: https://news.ycombinator.com/item?id=24992747 https://news.ycombinator.com/item?id=24992747 I understand this is not part of the stdlib. I do. But the officially blessed way without 3rd party crates is indeed quite hard to get right or to even write in one go. Another thing that severely disappointed me is the lack of serious plans for Rust 2021 Edition. I really was looking forward to a terser syntax for a bunch of idioms (sadly in the meantime they flew out of my head and now I can't remember them). The 6-week cycle is IMO not a problem. The changes have been fairly small -- but some of them very impactful, like the constant (pun intended) moving of functions from normal ones to `const` ones.
