Advent of Code 2025

Rusty and over-engineered edition.

Running

By request of AoC creator, I haven't included the input files (e.g. src/input/day01.txt). Log into the Advent of Code site and save the inputs there to the src/input/ folder.

Then to run: cargo run.

To run in super-fast prod mode: cargo run --release.

To run with debug logs enabled: RUST_LOG=debug cargo run.

To run the tests against included test input files: RUST_LOG=debug cargo test -- --no-capture.

Benchmarks

Because this is over-engineered, I've included benchmarks for each day's solution. Because, why not?

To run benchmarks: cargo bench.

Results

These were all run on my personal machine, an AMD Ryzen 9 3900X 12-Core Processor with 32 GB RAM, on Linux (WSL).

Timings are given as: [lower-bound best-estimate upper-bound]
