How to Check if a Constructor is Explicitly-Defaulted

For example:

struct X {
    X(){/***/}
    X(const int& ){/***/}
    X(      int&&){/***/}
    X(const X& ) = default;
    X(      X&&) = default;
    X& operator=(const X& ){/***/}
    X& operator=(      X&&){/***/}
};

Class X is not trivial and is not an aggregate.

Checking the source code of class X is not an option (although it is known which constructors and operators are available).

There is no trait in the library for this. It isn't possible to check with the help of the core language either.
