Struct template typeid_



// In header: <boost/type_erasure/builtin.hpp>

template<typename T = _self> 
struct typeid_ {


Enables runtime type information. This is required if you want to use any_cast or typeid_of.

[Note] Note

typeid_ cannot be specialized because several library components including any_cast would not work correctly if its behavior changed. There is no need to specialize it anyway, since it works for all types. typeid_ also cannot be passed to call. To access it, use typeid_of.
