The runner was adapted from this template. It uses the aoc-client crate, which requires a session cookie to interact with Advent of Code. This guide explains how to provide the session cookie.
The CLI helper can be invoked either with cargo run -- --help or
target/debug/aoc --help.
Note
I'm in the process of moving old solutions to the new runner setup.
New solutions are organized like src/{year}/{day}.rs.
