My solutions to Advent of Code, in Rust.

Use cargo test to check solutions. Puzzle tests are organized into modules with the naming convention y**::d**::test*, e.g.:

• cargo test to check all solutions for all years
• cargo test y21 to check 2021 solutions
• cargo test y21::d01 to check 2021, day 1
• cargo test y21::d01::test1 to check 2021, day 1, part 1
