Struct Board

pub struct Board { /* private fields */ }

Raw 9x9 board with some useful helpers.

There are multiple ways to create a Board:

• Using a 2D array of u8 with dimensions 9x9
• Using a 1D array of u8 with length 81
• Using a string representation with length 81

Implementations

impl Board

pub fn new(initial_board: [[u8; 9]; 9]) -> Self

pub fn get(&self, r: usize, c: usize) -> u8

Gets a value from the board at the specified row and column.

pub fn is_empty(&self, r: usize, c: usize) -> bool

Checks if a cell at the specified row and column is empty (contains 0).

pub fn iter_cells(&self) -> impl Iterator<Item = (usize, usize)> + '_

Iterates over all cells in the board, yielding their row and column indices.

pub fn iter_empty_cells(&self) -> impl Iterator<Item = (usize, usize)> + '_

Iterates over empty cells in the board, yielding their row and column indices.

Trait Implementations

impl Clone for Board

fn clone(&self) -> Board

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Board

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

Formats the value using the given formatter.

impl Default for Board

fn default() -> Board

Returns the “default value” for a type.

impl Display for Board

Formats the board into a human-readable string representation.

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

Formats the value using the given formatter.

impl PartialEq for Board

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

impl TryFrom<&str> for Board

type Error = RustokuError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<[u8; 81]> for Board

type Error = RustokuError

The type returned in the event of a conversion error.

fn try_from(bytes: [u8; 81]) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Board
