Advent of Code 2022

My solutions for the Advent Of Code 2022 puzzles written in Rust.

Can be found both on GitHub and my Gitea.

This code in organized with :

• A top-level crate to run tests and benchmarks
• Sub-level crates for each day (dayXX)
• A common crate for the common methods

In order to check those benchmarks, run cargo bench on the root crate.

Sub-level day crates

The sublevel day crates are both executable and libraries. The main logic is always implemented in lib.rs but a main method exists in main.rs to read the data file and show the answers. So, you can go to any day and run cargo run to see the day's answers.

dayXX
|- Cargo.toml
`- src/
   |- main.rs
   `- lib.rs

Tests

Every sub-level day crate contains tests for the examples given on that day. You can run cargo test in those day crates to see that examples are successfully processed.

The common crate

The common crate defines methods and macros used by multiple day crates :

• read_data : reads the data from the file into a String
• tests! : a macro designed to write quick unit tests based on an input and the expected output

Top-level tests and benchmarks

The metrics provided above are computed using cargo bench in the top-level crate. That crate also contains tests to check that the results of the computation are still valid for all days and parts.
