Struct template rebind_any



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

template<typename Any, typename T> 
struct rebind_any {
  // types
  typedef unspecified type;


A metafunction that changes the placeholder of an any. If T is not a placeholder, returns T unchanged. This class is intended to be used in concept_interface to deduce the argument types from the arguments of the concept.

 rebind_any<any<Concept>, _a>::type -> any<Concept, _a>
 rebind_any<any<Concept>, _b&>::type -> any<Concept, _b&>
 rebind_any<any<Concept>, int>::type -> int
