converting two types according to their typeid

[subkin13]

Hello,

boost::is_convertible<From, To> does it for types.
I need it for typeid's.
Meaning, is there a way to know if two types are convertible according to their typeid.

struct B {
B(const A& a) {}
};

struct A {};

boost::is_convertible<A,b>::value --> will be true.

i need something like this:

A a;
B b;

Is_Convertible(typeid(a),typeid(b));

Thanks
