Advent of Code 2021

These are puzzles for the Advent of Code 2021 challenge, written and solved in the Rust programming language.

The puzzle for each day is in its own folder in src/bin, and can be run using the following command (from the root folder):

cargo run --bin day1

If a particular day has tests, you can also run those:

cargo test --bin day1

The Puzzles

This year, I've put each day into its own folder because then I can give each its own README. I'll use this to write a little explanation of how it works, why I did something a certain way, or some other useful notes that may be helpful to people learning.
