std::is_execution_policy
From cppreference.com
| 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 std::execution::sequenced_policy, std::execution::parallel_policy, std::execution::parallel_unsequenced_policy, 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

true if T is a standard or implementation-defined execution policy type , false otherwise (public static member constant) |
Member functions
