Problem description

Here is the violating code snippet:

def remapper(length: int, idx: int) -> int:
            idx = int(idx)
            splits = [
                0,
                int(length * self.right_rear_front_split),
                int(length * self.halfway_split),
                int(length * self.left_front_rear_split),
            ]
            if splits[0] <= int(idx) < splits[1]:
                return int(splits[1] - splits[0]) - idx
            elif splits[2] <= int(idx) < splits[3]:
                return int(splits[3] - splits[2]) - (idx - splits[2]) + splits[2]
            else:
                return int(idx)

forward = forward_pattern.mapIndex(remapper)

according to the type in the binding code the types expected by mapIndex are typing.SupportsInt so this is not expected

Here is error according to vscode

Argument of type "(length: int, idx: int) -> int" cannot be assigned to parameter "indexMapper" of type "(SupportsInt, SupportsInt) -> int" in function "mapIndex"
  Type "(length: int, idx: int) -> int" is not assignable to type "(SupportsInt, SupportsInt) -> int"
    Parameter 1: type "SupportsInt" is incompatible with type "int"
