SA:MP Как преобразовать BitStream в структуру?

1. Любая

Имеем следующий код:

-- Функция отправки бистрима в чистом виде побайтово.
function sendTable(tab)
    local bs = raknetNewBitStream()
    for i = 1, #tab do
        raknetBitStreamWriteInt8(bs, tab[i])
    end

    raknetSendBitStream(bs)
end

sendTable({207, 0, 0, 0, 0, 4, 0, 90, 232, 188, 196, 22, 236, 78, 196, 36, 8, 113, 66, 78, 146, 84, 63, 0, 0, 0, 128, 0, 0, 0, 0, 180, 166, 14, 191, 117, 100, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 165, 4, 232, 128, 0})

-- Строка выше получена следующим образом, где array - это таблица.
function bitStreamStructure(bs)
    local text, array = '', {}
    for i = 1, raknetBitStreamGetNumberOfBytesUsed(bs) do
        local byte = raknetBitStreamReadInt8(bs)
        if byte >= 32 and byte <= 255 and byte ~= 37 then text = text .. string.char(byte) end
        table.insert(array, byte)
    end
    raknetBitStreamResetReadPointer(bs)
    return text, array
end

Мне нужно преобразовать данные для отправки по следующей структуре, используя Lua:

    struct stOnFootData
    {
        uint16_t    sLeftRightKeys;
        uint16_t    sUpDownKeys;
        union
        {
            uint16_t            sKeys;
            struct stSAMPKeys    stSampKeys;
        };
        float        fPosition[3];
        float        fQuaternion[4];
        uint8_t        byteHealth;
        uint8_t        byteArmor;
        uint8_t        byteCurrentWeapon;
        uint8_t        byteSpecialAction;
        float        fMoveSpeed[3];
        float        fSurfingOffsets[3];
        uint16_t    sSurfingVehicleID;
        short        sCurrentAnimationID;
        short        sAnimFlags;
    };
