NAME¶

std::is_execution_policy - std::is_execution_policy

Synopsis¶

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

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.

If the program adds specializations for std::is_execution_policy or
std::is_execution_policy_v, the behavior 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 = (since C++17)
std::is_execution_policy<T>::value;

Inherited from std::integral_constant

Member constants¶

value true if T is a standard or implementation-defined execution policy type,
[static] false otherwise
(public static member constant)

Member functions¶

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