Struct PromotionLogic

pub struct PromotionLogic;

Expand description

A stateless struct containing only static helper methods.

Implementations§

impl PromotionLogic

pub fn promote_pawn( mapping: &mut PieceMapping, occupied: &mut Occupied, captured_bits: &mut CapturedBits, pawn_pid: u8, color: u8, dest: u8, new_kind: u8, ) -> u8

Promote a pawn pawn_pid on dest (rank 0 or 7) to new_kind (0=queen,1=bishop,2=knight,3=rook). Uses fixed PIDs: • White: 14=queen, 12=bishop, 10=knight, 8=rook
• Black: 30=queen, 28=bishop, 26=knight, 24=rook
Updates mapping, occupied, and captured_bits. Returns the new PID.
