Advent of Code: Day One

It’s the first day of Advent of Code! I finally get to continue my long-standing tradition of being really enthusiastic about it for two-or-three days, missing one day, and not going back.

Today wasn’t too difficult, as it never is at the start. Once again I decided to use Rust, because I’d like to eventually be something close to competent with it. I spent way longer than intended on the code, absolutely convinced that there was a bug in the question, only to eventually realise that I’d misread the question.
