sizeof() Terminated raises an error instead of returning 0

[johnranson]

Per the docstring, "Size is defined as 0" for Terminated, but _sizeof simply raises an error.

I use sizeof in assert statements to verify that my Structs are exactly the length expected. If I include Terminated in a Struct, I get a SizeofError.

sizeof() broken in many different ways in construct.

I would just patch your code.

def _sizeof(self, context, path):
    return 0

construct.Terminated._sizeof = _sizeof
