shakmaty

A Rust library for chess move generation

Features

• Generate legal moves:

  ```rust use shakmaty::{Chess, Position, MoveList};

  let pos = Chess::default(); let legals = pos.legals(); assert_eq!(legals.len(), 20); ```

• Play moves:

  ```rust use shakmaty::{Square, Move, Role};

  // 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 magic attack tables.
