shakmaty

A Rust library for chess move generation

Features

• Generate legal moves:

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

• Play moves:

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

• 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 and Chess960. Provides vocabulary to implement other variants.

• Bitboards and compact fixed shift black magic attack tables.
