shakmaty

A Rust library for chess move generation

Features

• Generate legal moves:

  use shakmaty::Chess;
  use shakmaty::Position;
  use shakmaty::MoveList;
  
  let pos = Chess::default(); // starting position
  
  let mut legals = MoveList::new();
  pos.legal_moves(&mut legals);
  assert_eq!(legals.len(), 20);
  

• Play moves:

  use shakmaty::Move;
  use shakmaty::Role;
  use shakmaty::square;
  
  let pos = pos.play(&Move::Normal {
      role: Role::Pawn,
      from: square::E2,
      to: square::E4,
      capture: None,
      promotion: None,
  }).expect("1. e4 is legal");
  

• Detect game end conditions: pos.is_checkmate(), pos.is_stalemate(), pos.is_insufficient_material(), pos.outcome().

• Read and write FENs, SANs and UCIs.

• Supports Standard chess, Chess960, and these variants: Crazyhouse, King Of The Hill, Giveaway, Three-Check, Horde, Atomic, and Racing Kings.

• Bitboards and PEXT/PDEP attack tables.
