Too much kool-aid. Most programmers are not writing system code and they'd be much better served with languages like Go, Nim, and D. In fact, the example the author is trying to port over would have been much easier in Nim.

The actual question is then about the author learning a new paradigm and way of expressing system code. If that is the case these are just pains he has to go through because Rust will never be like Python for quick and dirty scripts, nor should it be.
