    Rust!!!!

    I think there's only 6 files I need to translate

    • [ ] Chess_Base.hpp
    • [ ] Chess_Test.hpp
    • [ ] Gigantua.cpp -> this will be separated into lib.rs and main.rs
    • [ ] Movegen.hpp
    • [ ] Movelist.hpp
    • [x] Movemap.hpp
    • [ ] I also plan to use the dual MIT-Apache license

    The commit history will be squashed since I obviously messed up

  • Halving link time while keeping run time performance

    Halving link time while keeping run time performance

    This PR halves the link time while maintaining the same run time performance.

    The template parameter inCheck in _enumerate is false if and only if checkmask == 0xffffffffffffffffull. So inCheck = (checkmask != 0xffffffffffffffffull).

    const map checkmask = ConstCheckmask<inCheck>(CheckMask);
    const map movableSquare = MoveableSquares<white, inCheck>(brd, checkmask);
    

    in _enumerate is equivalent to

    map movableSquare;
    if constexpr (inCheck) movableSquare = EnemyOrEmpty<white>(brd) & checkmask;
    else movableSquare = EnemyOrEmpty<white>(brd);
    

    which is equivalent to

    map movableSquare;
    if constexpr (checkmask != 0xffffffffffffffffull) movableSquare = EnemyOrEmpty<white>(brd) & checkmask;
    else movableSquare =EnemyOrEmpty<white>(brd) & checkmask;
    

    because in the else clause checkmask is 0xffffffffffffffffull, so the & does nothing. The branching is now redundant and the code snipped is equivalent to

    const map movableSquare = EnemyOrEmpty<white>(brd) & checkmask;
    

    Also every call to _enumerate is surrounded by a run time branching which determines the template parameter inCheck. This branching can be pulled into _enumerate and the template parameter replaced by a local variable. For the sake of simplicity I called it noCheck. Testing shows this doesn't hurt run time performance.

    The other commits just try to simplify the code. I hope it helps your productivity. Great work!
