I also switched from python to rust, and it sure was rough haha. The compiler is a stern but effective teacher; I felt like I was constantly fighting the language, but primarily because of my lack of understanding of ownership (not rust's fault!).

The Dijkstra stuff on day 15 is what ended it for me; like you said, python makes it easier to prototype stuff, so if you need to learn/relearn algorithms you never use day to day, it's so much more forgiving.
