31e5771d30 [board] Implement all the bit twiddling to track whether castling is allowed for each player and side of the board 2024-01-10 11:01:19 -08:00
359bab9173 [board] Implement rook::ClassicalMoveGenerator
Implement a rook move generator using the "classical" approach.
This approach walks each ray to find blockers and then masks out friendly pieces.
This is not efficient compared to other approaches, but it's much easier to implement.

No tests for Moves yet though.

19c48b9816 [board] Implement a DiagramFormatter that writes a graphical diagram of a Position

758a3d95fc [board] Reorganize bitboard and position modules and export some symbols from the crate
Move position.rs to the position module and create a mod.rs.

Export Color, Piece, Position, and Square and use crate::Thing directly instead of referring to the symbol in the nested modules.
