Struct Candidates

pub struct Candidates { /* private fields */ }

Represents the candidates cache for a Rustoku puzzle.

This struct holds a 9x9 grid of candidate masks for each cell in the Rustoku board. Each cell’s candidates are represented as a bitmask, where each bit corresponds to a number from 1 to 9. A bit set to 1 indicates that the corresponding number is a candidate for that cell. This struct provides methods to get and set candidate masks for specific cells, as well as to update the candidates based on the current state of the board and masks.

Implementations

impl Candidates

pub fn get_candidates(&self, r: usize, c: usize) -> Vec<u8>

Returns the actual candidate numbers (1-9) for a specific cell.

Trait Implementations

impl Clone for Candidates

fn clone(&self) -> Candidates

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Candidates

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

Formats the value using the given formatter.

impl PartialEq for Candidates

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

Tests for self and other values to be equal, and is used by ==.

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

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