std::promise
template < class R, class Alloc >
struct uses_allocator< std::promise <R>, Alloc> : std::true_type { } ;
(since C++11)

Provides a specialization of the std::uses_allocator type trait for std::promise

Inherited from std::integral_constant

Member constants

value
[static]
 true
(public static member constant)

Member functions

operator bool
 converts the object to bool, returns value
(public member function)
operator()
(C++14)
 returns value
(public member function)

Member types

Type Definition
value_type bool
type std::integral_constant < bool, value>
