Well - of course I prefer a centralized package manager like pacman, which I also use for python packages etc., but I mainly dislike the building process of rust, which is usually done with cargo. No libraries, not even a global cache for already compiled dependencies, no distcc. This makes it infinitely slower than most C/C++ projects. Compiling the kernel is literally faster than compiling a "simple" project like spotify_cli (500+ dependencies, depending on configuration).

So it's ass from a user perspective, waiting for stuff to compile (just for it to fail, and start from scratch, as some stuff needs a clean build/src dir), and imo very weird from a dev perspective.
