# Advent of Code 2022 in Rust
My [Advent of Code 2022][aoc-2022] solutions in the Rust programming language.
This repository holds a separate Rust project for each day and part.
I attempt to develop a standalone, elegant, compact and fast solution for each
problem (two each day).
Previous year I did the same, solving everything in under a second:

- https://github.com/timvisee/advent-of-code-2021
- https://github.com/timvisee/advent-of-code-2020
## Timings
Here is how long each solution runs. All solutions are measured (non
scientifically) in [`bench.rs`](./runner/src/bin/bench.rs) on an
`AMD Ryzen 9 5900X (24) @ 3.7GHz` machine running Linux.

## Run solutions
Each Rust project contains a `input.txt` file, holding the puzzle input. Simply
run the project to see the solution appear.
```bash
# Switch to day 1a, and run it
cd day01a
cargo +nightly run --release
# or run everything in parallel
cd ../runner
cargo +nightly run --release --bin runner-par
# or benchmark every day
cd ../runner
cargo +nightly run --release --bin bench
```
Some solutions require Rust Nightly, that's why `+nightly` is included.
