std::is_execution_policy: std::is_execution_policy

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.
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 > (since C++17)
inline constexpr bool is_execution_policy_v = std::is_execution_policy<T>::value;


Inherited from std::integral_constant

Member constants
