### uses_executor

The `uses_executor` trait detects whether a type T has an associated executor that is convertible from type Executor.

    template<
        typename T,
        typename Executor>
    struct uses_executor :
      public false_type

Meets the BinaryTypeTrait requirements. The Asio library provides a definition that is derived from false_type. A program may specialize this template to derive from true_type for a user-defined type T that can be constructed with an executor, where the first argument of a constructor has type `executor_arg_t` and the second argument is convertible from type Executor.
