## While perhaps not the best way, this worked fine in strawberry v74.x

## module1, to keep strawberry stuff out

def parse_slice_size(val: int) -> types.PositiveInt:
    assert isinstance(val, int), "Input must be of type int"

    if val > config.settings.max_slice_size or val < 1:
        raise ValueError(f"Must be between 1 and (including) {config.settings.max_slice_size}")
    return types.PositiveInt(val)
  

PositiveInt = NewType("PositiveInt", int)
PositiveInt.__doc__ = "Zero or a positive-only integer"

## module2, all strawberry'isms on top off the base classes
strawberry.scalar(
    types.PositiveInt,
    serialize=lambda x: int(x),
    parse_value=types.parse_slice_size,
    description=types.PositiveInt.__doc__,
)
