struct Scratchcard {
    winning_numbers: HashSet<i32>,
    numbers_you_have: HashSet<i32>,
}

Represents a scratchcard (one line of input)

Fields

winning_numbers: HashSet<i32>

numbers_you_have: HashSet<i32>

Implementations

impl Scratchcard

fn match_count(&self) -> usize

The number of numbers you have that match a winning number

fn score(&self) -> i32

The first match scores one, each subsequent match doubles the score

Trait Implementations

impl Debug for Scratchcard

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl From<&str> for Scratchcard

fn from(value: &str) -> Self

Parse a string in the format Card 1: 41 48 83 86 17 | 83 86 6 31 17 9 48 53

impl PartialEq<Scratchcard> for Scratchcard

fn eq(&self, other: &Scratchcard) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
