Struct zero_sum::impls::tic_tac_toe::Board

pub struct Board(pub [Option<Mark>; 9], pub u8);

The 3x3 game board.

Methods

impl Board

fn new() -> Board

Creates an empty board.

fn next_mark(&self) -> Mark

Returns the mark that will make the next move.

Trait Implementations

impl Display for Board

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

Formats the value using the given formatter.

impl State for Board

type Ply = Ply

type Resolution = Resolution

fn get_ply_count(&self) -> usize

Returns the number of plies that have passed in the game.

fn execute_ply(&mut self, ply: Option<&Ply>) -> Result<(), String>

Executes the given ply on this state. Pass None to execute a null move.

fn revert_ply(&mut self, ply: Option<&Ply>) -> Result<(), String>

Reverts the given ply from the state. Pass None to revert a null move.

fn check_resolution(&self) -> Option<Resolution>

Returns None if the game has not reached a conclusion.

fn null_move_allowed(&self) -> bool

Returns true if the state is in a good place to allow the null move search optimization. This is optional to implement, returning a default of false.

fn execute_plies(&mut self, plies: &[Self::Ply]) -> Result<(), String>

Executes each ply in plies on the result of the previous ply.

impl Extrapolatable<Ply> for Board

fn extrapolate(&self) -> Vec<Ply>

Returns a list of plies that should be considered from the current state. The search system does not assume that all plies returned are correct.

impl Clone for Board

fn clone(&self) -> Board

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Board

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for Board

impl PartialEq for Board

fn eq(&self, __arg_0: &Board) -> bool

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

fn ne(&self, __arg_0: &Board) -> bool

This method tests for !=.

impl Hash for Board

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

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].
