Tuple Fields

0: [bool; 33]

Implementations

impl Board

const LINE_OFFSET: [usize; 7]

pub fn index_for([x, y]: [isize; 2]) -> Option<usize>

Trait Implementations

impl ArrayBoard for Board

const ROW_START_IDX: [usize; 7]

fn get_idx(&self, idx: usize) -> bool

Gets the value of the board at the given index.

fn set_idx(&mut self, idx: usize, value: bool) -> bool

Sets the value of the board at the given index and returns the old value.

const ROW_LENGTH: [usize; 7] = _

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

Formats the board as a string, using “●” for occupied and “○” for empty locations. The board is surrounded by a border.

impl Board for Board

fn new_start() -> Self

Start configuration of a game

fn get(&self, [x, y]: [isize; 2]) -> Option<bool>

Gets the value of the board at the given (x, y) location, where (0, 0) is the top left corner. Returns None if the location is invalid.

fn set(&mut self, idx: [isize; 2], value: bool) -> Option<bool>

Sets the value of the board at the given (x, y) location, where (0, 0) is the top left corner. Returns the old value, or None if the location is invalid.

fn get_legal_moves(&self) -> Vec<Self>

Gets all legal moves from the current board state. A move is legal if it consists of a marble jumping over an adjacent marble into an empty space, and the jumped-over marble is removed.

fn marble_count(&self) -> u32

Counts the number of marbles currently on the board.

fn mirror_horizontal(&self) -> Self

fn mirror_vertical(&self) -> Self

fn transpose(&self) -> Self

fn is_solved(&self) -> bool

Checks if the board is in a solved state, meaning that there is only one marble left.

fn get_symmetries(&self) -> [Self; 8]

Returns an array of all 8 symmetries of the board, including the board itself. The symmetries are generated by mirroring horizontally, mirroring vertically, and transposing the board in all combinations.

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 Display for Board

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

Formats the value using the given formatter.

impl Hash for Board

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
