My attempts at the Advent of Code 2021 challenges.
My goal is using these as exercises to continue learning Rust. So I don't expect to get on the leaderboards (especially because I'm starting a few days late). I also plan to prioritize exploring Rust features, libraries and/or coding standards over other concerns. In particular, much of this will be intentionally over-complicated for the task at hand, and I probably won't code-golf most of the solutions.
