You shouldn’t take your opinions on things from HN discussions that claim that Rust is changing quickly, and then are only able to point out 3 things over 5 years that have changed.
I don't. Crate authors seems to be playing catch up to, or more likely, abandon their old work. I'ts really hard coming in to Rust to get a feel for what to use in any given situation as the crates are either dead or in alpha.
