rust

This is a collection of my personal solutions for Advent of Code 2021.

For this year, I'm using AoC2021 as an outlet for learning Rust.

Benchmarks

$ cargo aoc bench

Solutions and benchmarks are run on a t6g.medium Graviton2 instance on AWS EC2.

Variants marked as original were my first working solutions when I submitted them to the AoC event --- all subsequent variants in the same problem are just me trying out other approaches (most of the time because I learned something new since my initial solve.)
