Struct Puzzle

pub struct Puzzle<T, D> { /* private fields */ }

The Puzzle struct stores information for an aoc puzzle. Two puzzles release each aoc day.

Implementations

impl<T, D: Display> Puzzle<T, D>

pub fn new(part: u8, solver: fn(T) -> D) -> Self

Create a new Puzzle instance for the provided part number and solver function.

Example

use aoc_helper::Puzzle;

let part_1 = Puzzle::new(1, |x| x.lines().count());

Examples found in repository

examples/2015_day1.rs (lines 25-29)

fn main() {
    // NOTE: You need to specify a session ID for this to work

    // Create a new `AocDay` instance for day 1 of aoc 2015
    let mut day_1 = AocDay::new(2015, 1);

    // Create a new `Puzzle` instance for part 1
    let part_1 = Puzzle::new(1, |instructions: String| {
            let mut floor = 0;
            instructions.chars().for_each(|x| if x == '(' { floor += 1 } else { floor -= 1 });
            floor
        })
        .with_examples(&["(())", "()()", ")))", ")())())"]);

    // Create a new `Puzzle` instance for part 2
    let part_2 = Puzzle::new(2, first_instruction_that_sends_to_basement)
        .with_examples(&[")", "()())"]);

    // Test the example cases
    day_1.test(&part_1);
    day_1.test(&part_2);
    // Run the day's input
    day_1.run(&part_1).unwrap();
    day_1.run(&part_2).unwrap();
}

pub fn examples<S: ToString>(&mut self, examples: &[S])

Provide some example inputs for a Puzzle instance that the solver function will be given when AocDay::test() is called.

Example

use aoc_helper::Puzzle;

let mut part_2 = Puzzle::new(2, |x| x.lines().nth(0).unwrap());
part_2.examples(&["example\ninput", "foo\nbar"]);

pub fn with_examples<S: ToString>(self, examples: &[S]) -> Self

Chainable version of Puzzle::examples()

Example

use aoc_helper::Puzzle;

let part_2 = Puzzle::new(2, |x| lines().nth(0).unwrap())
    .with_examples(&["example\ninput", "foo\nbar"]);
