My Rust solutions for the first 11 days of Advent of Code 2018.

To run a particular day, the run_day function in main.rs can be used:

// Run star 1 of day 3
run_day(3, Some(1));
// Run star 2 of day 5
run_day(5, Some(2));
// Run star 3 of day 11
run_day(3, None);

By default, the main function runs all days. Usage:

cargo run --release

Output:
