Defined in header <execution>
template< class T > struct is_execution_policy;		(since C++17)

Checks whether T is a standard or implementation-defined execution policy type.

Provides the member constant value which is equal to true, if T is a standard execution policy type, or an implementation-defined execution policy type. Otherwise, value is equal to false.

The behavior of a program that adds specializations for std::is_execution_policy is undefined.

Template parameters

T

-

a type to check

Helper template

Defined in header <execution>
template< class T > inline constexpr bool is_execution_policy_v = std::is_execution_policy<T>::value;		(since C++17)

Inherited from std::integral_constant

Member constants

value [static]

true if T is a standard or implementation-defined execution policy type, 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>
