Solutions to all 25 AoC 2020 problems in Rust :crab:

This year I went all out and went up at 5:50 every single day (except day 5 when I overslept :cry:) to do the puzzles. I tried to aim for relatively high scores on the leaderboard and got as high as 116 on day 20, however competing against Python with Rust is difficult. Solved most problems in less than one hour though, and consistently hit top 1000 on a lot of the problems. This year was cool but a lot easier than 2019.

See notes.md for some thoughts I wrote down after completing each day.

See timings.md for the execution time of each solution.

Thanks for another amazing year of AoC @ericwastl :christmas_tree:
