Implementations

impl Piece

pub fn to_index(&self) -> usize

Convert the Piece to a usize for table lookups.

pub fn to_string(&self, color: Color) -> String

Convert a piece with a color to a string. White pieces are uppercase, black pieces are lowercase.

use chess::{Piece, Color};

assert_eq!(Piece::King.to_string(Color::White), "K");
assert_eq!(Piece::Knight.to_string(Color::Black), "n");

impl Ord for Piece

fn cmp(&self, other: &Piece) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Piece> for Piece

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Piece> for Piece

fn partial_cmp(&self, other: &Piece) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool
