My rust solutions to Advent of Code puzzles.

This project uses aoc-runner and cargo-aoc

cargo-aoc does not support workspaces and multi-year projects, so you have to run them as binaries.

cargo build
cargo run --bin aoc2021

To run a release version add --release to the above arguments

To run tests:

cargo test

cargo-aoc can be used to get your input data, you need to set your aoc web session id with

cargo aoc credentials -s {token}  # get this from Application tab in chrome tools for aoc website

then you can just run

cargo aoc input [ -d {day} -y {year} ] # defaults to today's date
cargo aoc input -d 4 -y 2021

To parse the input quickly, use #[aoc_generator(dayX}] and implement a function that will convert the data input file to types required. e.g. for day 01, a list of strings that need to be converted to integers:

#[aoc_generator(day1)]
pub fn input_generator(input: &str) -> Vec<u32> {
    common::input_vec(input)
}

Other examples are in the cargo_aoc docs and in the worked solutions, e.g. src/day_03.rs
