Advent of Code 2024 in Rust

My Advent of Code 2024 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).

Three 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.

part A part B
day 1 0.021 ms 0.022 ms
day 2 0.034 ms 0.073 ms
day 3 0.118 ms 0.206 ms
day 4 0.148 ms 0.026 ms
one-by-one (1 CPU core) parallel
everything 0.78 ms 0.26 ms

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.
