Struct Masks

pub struct Masks { /* private fields */ }

Masks for Rustoku puzzle, representing the state of rows, columns, and boxes.

This struct holds bitmasks for each row, column, and 3x3 box in the Rustoku board. Each bit in the masks corresponds to a number from 1 to 9, where a bit set to 1 indicates that the corresponding number is present in that row, column, or box.

Implementations

impl Masks

pub fn is_safe(&self, r: usize, c: usize, num: u8) -> bool

Checks if a number can be safely placed in the specified cell.

Trait Implementations

impl Clone for Masks

fn clone(&self) -> Masks

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Masks

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

Formats the value using the given formatter.

impl PartialEq for Masks

fn eq(&self, other: &Masks) -> 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.
