Advent of Code 2015

In preparation for Advent of Code 2021, I wanted to go back and try some of the older challenges. I figured it made the most sense to start from the very beginning.

I will be trying to do all 25 challenges in Rust both for the challenge and to gain experience with it. I will also be attempting to be as "proper" as possible: just because I know my puzzle inputs are all valid doesn't mean I won't catch and handle errors—each day will produce a full binary application that can run any given input.

Hopefully I don't break and have to resort to JavaScript 😁
