TIsBitwiseConstructible

Tests if a type T is bitwise-constructible from a given argument type U. That is, whether or not the U can be memcpy'd in order to produce an instance of T, rather than having to go via a constructor.

Examples: TIsBitwiseConstructible<PODType, PODType >::Value == true // PODs can be trivially copied TIsBitwiseConstructible<const int, int >::Value == true // a non-const Derived pointer is trivially copyable as a const Base pointer TIsBitwiseConstructible<int, const int>::Value == false // not legal the other way because it would be a const-correctness violation TIsBitwiseConstructible<int32, uint32 >::Value == true // signed integers can be memcpy'd as unsigned integers TIsBitwiseConstructible<uint32, int32 >::Value == true // and vice versa
