Meta-programming detecting anonymous unions inside structs.

I am trying to port a serialization library I wrote in Lua some
time ago. I've ran into a problem relating to types with
anonymous unions inside.
Given this code:
enum Kind
{
none = 0,
array,
integer,
floating,
}
struct Foo
{
Kind type;
union
{
ulong integer;
double floating;
void[] array;
}
int nonUnionField;
//...
}
How can I tell that "integer", "floating" and "array" are part
the union while "nonUnionField" is not?
Thanks in advance.
