aoc-star-derive

Procedural macro crate for aoc-star.

You normally don't use this crate directly. Instead, depend on aoc-star, and import the star attribute from there:

use aoc_star::star;

#[star(day = 1, part = 1, year = 2024)]
fn solve_day1_part1(input: String) -> String {
    // ...
    "answer".to_string()
}

The star attribute:

• Registers the annotated function as an Advent of Code solution for a given day, part, and optional year.
• Ensures that the function has the correct signature: it must accept a single String argument (the puzzle input) and return a String (the answer).
• Uses the inventory crate to make the solution discoverable at runtime.
