std::is_execution_policy
Defined in header <execution> |

(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 or std::is_execution_policy_v is undefined.
