Template std.traits.Fields
Get as a tuple the types of the fields of a struct, class, or union.
This consists of the fields that take up memory space,
excluding the hidden fields like the virtual function
table pointer or a context pointer for nested types.
If T isn't a struct, class, or union returns a tuple
with one element T.
Arguments
template Fields(T);
Example
struct S { int x; float y; }
static assert(is(Fields!S == TypeTuple!(int, float)));
