Kernel functor requirements:

struct MyFunctor         
{
    template<
        typename TAcc>         // Templated on the accelerator type.
    ALPAKA_FCT_ACC             // Macro marking the function to be executable on all accelerators.
    void operator()(           // The function / kernel to execute.
        TAcc const & acc,      // The interfaced accelerator implementation.
        ... ) const                  
    {
        ... 
    }
    
    // Class can have members but has to be std::is_trivially_copyable.
    // Classes must not have pointers or references to host memory!
};
