Advent of Code 2023 in Rust
My Advent of Code 2023 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).
Two years ago I did the same, solving everything in under a second:

Timings
Here is how long each solution runs with my input. All solutions are measured
(non scientifically) in bench.rs on an AMD Ryzen 9 5900X (24) @ 3.7GHz machine running Linux.

Run solutions
Each Rust project needs a input.txt file to run, holding the puzzle input.
Simply create this file with your input and run the project to see the solution
appear.
# Switch to day 1a, add input, and run it
cd day01a
nano input.txt
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.
Sadly I cannot include my puzzle input anymore to make each solution easily runnable as per Advent of Code FAQ:
If you're posting a code repository somewhere, please don't include parts of Advent of Code like the puzzle text or your inputs.
