Passing list of functions as an arg in python class constructor

Numba Support: How do I do ...?
1

This is my definition of constructor

list_of_float_or_int = List[Union[float, int]]
type_constraints = List[Tuple[Union[int, float, None], Union[float, int, None]]]
@jitclass(spec=[
    ('lb', types.ListType(types.UnionType((types.int64, types.float64)))),
    ('ub', types.ListType(types.UnionType((types.int64, types.float64)))),
    ('constraints', types.ListType(
        types.ListType(
            types.UnionType(
                (types.int64, types.float64, types.none)
                        )
                )
            )
     ),
    ('penalty_parameter', types.int64),
    ('current_iteration', types.int64),
    ('wolf_pack_size', types.int64),
    ('num_of_iterations', types.int64),
    # ('constraints_func', types.ListType(types.Function)),
    # ('objective_func', types.Function),
])
class GreyWolfOptimizer(object):

    def __init__(
            self,
            wolf_pack_size: int, num_of_iterations: int, num_of_params: int, objective_func: Callable,
            ub: list_of_float_or_int,
            lb: list_of_float_or_int,
            constraints_func: List[Callable],
            constraints: type_constraints,
            comparator: Callable,
            dtype: Type[Union[float, int]] = float,
            dtypes: List[Type[Union[float, int]]] = None
    ):

but when i try to run it I get

- argument 3: Cannot determine Numba type of <class 'function'>
- argument 6: Cannot type list element type <class 'function'>
- argument 8: Cannot determine Numba type of <class 'function'>
- argument 9: Cannot determine Numba type of <class 'type'>
- argument 10: Cannot type list element type <class 'type'>

which makes sense since numba doesn’t know about function
is there a way to solve this?

Does this help?
