Struct template rebind_any

boost::type_erasure::rebind_any

Synopsis

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

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

Description

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>, _c&&>::type -> any<Concept, _c&&>
rebind_any<any<Concept>, int>::type -> int
