If an imaginary rvalue of type From can used in the return statement of a function returning To, that is, if it can be converted to To using implicit conversion, provides the member constant value equal to Template:cpp. Otherwise value is Template:cpp.

Inherited from std::integral_constant

Member constants

value
[static]
true if From is convertible to To , false otherwise
(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>

Notes

Gives well-defined results for reference types, void types, array types, and function types.
