Implementations

impl KTable

pub fn add(&mut self, ply: u16, move: Move)

Adds a new killer r#move at the level specified by ply value. Maximal amount of slots for each of them is set by KILLER_SLOTS constant, and newer entries have always a priority over old ones. If there’s already exactly the same move in the slot 0, the table is not changed.

pub fn get(&self, ply: u16) -> [Move; 2]

Gets all killer moves at the level specified by ply.

pub fn age_moves(&mut self)

Ages killer table by shifting all ply levels by two positions up, to ensure that killer moves inside match board after two halfmoves.

Trait Implementations
