}

Piece types: Pawn, Knight, Bishop, Rook, Queen, King.

Examples

use shakmaty::Role;

// Piece types are indexed from 1 to 6.
assert_eq!(u32::from(Role::Pawn), 1);
assert_eq!(u32::from(Role::King), 6);

Variants

Pawn = 1

Knight = 2

Bishop = 3

Rook = 4

Queen = 5

Implementations

impl Role

pub const ALL: [Role; 6]

Examples

use shakmaty::Role;

assert_eq!(Role::from_char('K'), Some(Role::King));
assert_eq!(Role::from_char('n'), Some(Role::Knight));

assert_eq!(Role::from_char('X'), None);

pub const fn of(self, color: Color) -> Piece

Gets a Piece of the given color.

Examples

use shakmaty::{Color, Role};

assert_eq!(Role::King.of(Color::Black), Color::Black.king());

pub const fn char(self) -> char

Gets the English letter for the piece type.

Examples

use shakmaty::Role;

assert_eq!(Role::Rook.char(), 'r');

pub const fn upper_char(self) -> char

Gets the uppercase English letter for the piece type.

Examples

use shakmaty::Role;

assert_eq!(Role::Rook.upper_char(), 'R');

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a copy of the value.

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

impl Debug for Role

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

Formats the value using the given formatter.

impl Hash for Role

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)

impl Ord for Role

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
