小编use*_*721的帖子

我用google搜索"←"并在这里搜索它,找不到任何东西.但是我找到了这个国际象棋游戏的源代码.在这里查看.大量使用此符号的代码块示例:

 for {
      storedFen ? GameRepo initialFen game
      fen = storedFen orElse (aiVariant match {
        case v@Horde => v.initialFen.some
        case _       => none
      })
      uciMoves ? uciMemo get game
      moveResult ? move(uciMoves.toList, fen, level, aiVariant)
      uciMove ? (UciMove(moveResult.move) toValid s"${game.id} wrong bestmove: $moveResult").future
      result ? game.toChess(uciMove.orig, uciMove.dest, uciMove.promotion).future
      (c, move) = result
      progress = game.update(c, move)
      _ ? (GameRepo save progress) >>- uciMemo.add(game, uciMove.uci)
    } yield PlayResult(progress, move)
