  • Ah I didn’t realize most people have moved onto OnceCell. The issue with both lazy static and oncecell is that they can only be assigned to once. You need a global mutable state, so neither OnceCell or lazy_static are the right choice.

    You’re going to be fighting the borrow checker if you try to have global mutable state. It will bite you eventually. You can potentially use an interior mutablity pattern along with a mutex. Have you looked into interior mutability?







  • Ideally, all of these values should be represented in memory exactly the same way:

    That would make the game hard to play, since you’d have to think about where your move would end up since it won’t stay on the cell you click.

    I think you’re wanting to store them that way so that you can easily check for win conditions, maybe? But that’s the wrong approach. Store the cells as they appear to the player, in a 2d Array (or 1d Array with indexing math. That’s how I’d do it).

    Then you can take advantage of symmetries in your win condition code, if you like. But it really couldn’t be much simpler than counting the matching cells in each row, column, and diagonal. That’s just 8 groups of 3.
