The execution::is_executor trait detects whether a type T satisfies the execution::executor concept.

template<
    typename T>
struct is_executor :
  public integral_constant< bool, automatically_determined >

Class template is_executor is a UnaryTypeTrait that is derived from true_type if the type T meets the concept definition for an executor, otherwise false_type.
