Methods

impl PieceType

fn iter() -> PieceTypeIter

Returns an iterator over all variants.

fn from_sfen(c: char) -> Option<PieceType>

Creates a new instance of PieceType from SFEN formatted string.

fn promote(&self) -> Option<PieceType>

Returns an instance of PieceType after promotion.

Examples

use shogi::PieceType;

assert_eq!(Some(PieceType::ProPawn), PieceType::Pawn.promote());
assert_eq!(None, PieceType::ProPawn.promote());

fn unpromote(&self) -> Option<PieceType>

Returns an instance of PieceType before promotion.

Examples

use shogi::PieceType;

assert_eq!(Some(PieceType::Pawn), PieceType::ProPawn.unpromote());
assert_eq!(None, PieceType::Pawn.unpromote());

fn is_hand_piece(&self) -> bool

Checks if this piece type can be a part of hand pieces.

fn index(&self) -> usize

Converts the instance into the unique number for array indexing purpose.
