The .tupleof field allows you to access private members. This behavior
might eventually change, but probably not without a long deprecation
period.
If the struct stores everything by value:
cast(ubyte[])&rng[0..1];
If you have typeinfo available, you can check if the thing has pointers
with `(typeof(rng).flags & 1) == 0`. There's probably an equivalent in
std.traits that works at compile time.
