Attempt at solving some Advent of Code 2022 puzzles using Rust which I have never used before.

Thanks to MetroWind/advent2019 and fspoettel/advent-of-code-rust for inspiration on how to structure the project.

Adding a day

Auto

Run cargo start-day n where n is the day number

Manual

Let us say you are adding day 4

• Add files inputs/day4.txt and example_inputs/day4.txt and add AOC input
• Add pub mod day4; into the mod days {...} block in main.rs
• Add "4" => Box::new(days::day4::Day4 {}), into the match n {...} block in main.rs
• Create file src/days/day4.rs and implement the Day trait like so:

use crate::days::day;
use crate::days::day::Input;

pub struct Day4 {}

impl day::Day for Day4 {

    fn part_one(&self, input: &Input) -> String {
        return "p1".to_string();
    }

    fn part_two(&self, input: &Input) -> String {
        return "p2".to_string();
    }
}

• The type Input passed into part_one and part_two is defined in day.rs, and has two useful methods on it - as_string and as_list. These will get you the relevant day's input parsed as either a String or a Vec<String>. See below for how to use real or example input.
