Implementations

impl CastleZone

pub fn side(&self) -> Side

Return the side which this zone belongs to.

pub fn kingside(side: Side) -> CastleZone

Return the kingside zone for the given side.

pub fn queenside(side: Side) -> CastleZone

Return the queenside zone for the given side.

pub fn iter() -> impl Iterator<Item = CastleZone>

Create an iterator traversing all zones in order.

pub fn source_squares(self) -> BitBoard

Returns a set of exactly two squares which denote the required locations of the king and rook in order for the corresponding castle move to take place.

pub fn rook_data(self) -> (Piece, Square, Square)

Returns a triple containing the rook which moves in the corresponding castle move along with it's required start square followed by the square it will finish on.

pub fn king_data(self) -> (Piece, Square, Square)

Returns a triple containing the king which moves in the corresponding castle move along with it's required start square followed by the square it will finish on.

pub fn unoccupied_requirement(self) -> BitBoard

Returns a set containing the squares which are required to be free of any other pieces in order for the corresponding castle move to be legal.

pub fn uncontrolled_requirement(self) -> BitBoard

Returns a set containing the squares which are required to be free of enemy control in order for the corresponding castle move to be legal.

pub fn lift(self) -> CastleZoneSet

Lifts this zone to a set of one element.
