Advent of Code 2022 in Rust
My Advent of Code 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:

Timings
Here is how long each solution runs. All solutions are measured (non
scientifically) in bench.rs on an
AMD Ryzen 9 5900X (24) @ 3.7GHz machine running Linux.
| one-by-one (1 CPU core) | parallel | |
|---|---|---|
| everything | 81.32 ms |
51.86 ms |
Run solutions
Each Rust project contains a input.txt file, holding the puzzle input. Simply
run the project to see the solution appear.
# 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 benchSome solutions require Rust Nightly, that's why +nightly is included.
