Advent of Code 2022 Commands
    login             # Login to Advent of Code (Use AOC_SESSION_TOKEN environment variable)
    new DAY           # Start a new solution for day number DAY
    run DAY           # Run the solution for day number DAY
    run-sample DAY    # Run a solution with a sample input file (place in `samples/2022/day{{DAY}}.txt`)
    run-benchmark DAY # Benchmark the solution for day number DAY

Benchmarks

cargo-aoc benchmarks generator functions, which parse the project input, and solution functions, which contain the actual problem solving logic.
