Trait advent_of_code_traits::ParseInput[−][src]

pub trait ParseInput<const Day: u32> {
    type Parsed;
    fn parse_input(input: &str) -> Self::Parsed;
}

Implement this trait to parse the the day’s input into a type.

This trait is generic over day.

See ParseEachInput if you want to use a different input type for each part of a day.

Example Usage

use advent_of_code_traits::{days::Day1, Part1, Part2, ParseInput};
pub struct AdventOfCode2020;

impl ParseInput<Day1> for AdventOfCode2020 {
    type Parsed = Vec<usize>;

    fn parse_input(input: &str) -> Self::Parsed {
        // parse your input for day 1
        input.lines()
            .map(|n| n.len())
            .collect()
    }
}

let part1_input = <AdventOfCode2020 as ParseInput<Day1>>::parse_input("input");
let part2_input = <AdventOfCode2020 as ParseInput<Day1>>::parse_input("input");

// both parts get the same input
assert_eq!(part1_input, part2_input);
