Implementations

impl Piece

pub fn from_sfen(c: char) -> Option<Piece>

Creates a new instance of Piece from SFEN formatted string.

pub fn promote(self) -> Option<Piece>

Returns an instance of Piece after promotion.

Examples

use shogi::{Color, PieceType, Piece};

let pc1 = Piece{piece_type: PieceType::Pawn, color: Color::Black};
let pc2 = Piece{piece_type: PieceType::ProPawn, color: Color::Black};

assert_eq!(Some(pc2), pc1.promote());
assert_eq!(None, pc2.promote());

pub fn unpromote(self) -> Option<Piece>

Returns an instance of Piece before promotion.

Examples

use shogi::{Color, PieceType, Piece};

let pc1 = Piece{piece_type: PieceType::Pawn, color: Color::Black};
let pc2 = Piece{piece_type: PieceType::ProPawn, color: Color::Black};

assert_eq!(Some(pc1), pc2.unpromote());
assert_eq!(None, pc1.unpromote());

pub fn flip(self) -> Piece

Returns an instance of Piece with the reversed color.

Examples

use shogi::{Color, PieceType, Piece};

let pc1 = Piece{piece_type: PieceType::Pawn, color: Color::Black};
let pc2 = Piece{piece_type: PieceType::Pawn, color: Color::White};

assert_eq!(pc2, pc1.flip());
assert_eq!(pc1, pc2.flip());
