Struct chess_move_gen::MoveCounter

pub struct MoveCounter {
    pub moves: u8,
    pub captures: u8,
    pub castles: u8,
    pub promotions: u8,
    pub ep_captures: u8,
}

MoveCounter implements MoveList and keeps a count of different types of moves added to it. It can count at most 256 moves since it uses u8 internally

Fields

moves: u8

captures: u8

castles: u8

promotions: u8

ep_captures: u8

Methods

impl MoveCounter

pub fn new() -> MoveCounter

Trait Implementations

impl Debug for MoveCounter

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for MoveCounter

fn clone(&self) -> MoveCounter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for MoveCounter

impl PartialEq for MoveCounter

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

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

fn ne(&self, other: &MoveCounter) -> bool

This method tests for !=.

impl MoveList for MoveCounter

fn add_moves(&mut self, _: Square, targets: BB, enemy: BB)

Adds moves from the from-square. Targets is a bitboard of valid to-squares. Enemy is a bitboard of enemy pieces (ie pieces that can be captured)

fn add_castle(&mut self, _: Castle)

Adds the castle to the move list

fn add_pawn_ep_capture(&mut self, _: Square, _: Square)

Adds pawn en-passant capture to list. From and to are the squares the moving pieces moves from and to, respectively

fn add_pawn_pushes(&mut self, _: usize, targets: BB)

Adds pawn non-captures to the list. Targets is a bitboard of valid to-squares. Shift is the distance the pawn moved to get to the target square, mod 64. For example, for a white piece moving forward one row this is '8'. For a black piece moving forward one row this is 56 (-8 % 64).

fn add_pawn_captures(&mut self, _: usize, targets: BB)

Adds pawn captures to list. Targets and shift are same as for add_pawn_pushes. Do not use this for en-passant captures (use add_pawn_ep_capture)
