<p>
        The <a class="link" href="uses_executor.html" title="uses_executor"><code class="computeroutput">uses_executor</code></a>
        trait detects whether a type T has an associated executor that is convertible
        from type Executor.

<pre class="programlisting">template&lt;
    typename T,
    typename <a class="link" href="Executor1.html" title="Executor requirements">Executor</a>&gt;
struct uses_executor
</pre>
<p>
        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 <a class="link" href="executor_arg_t.html" title="executor_arg_t"><code class="computeroutput">executor_arg_t</code></a>
        and the second argument is convertible from type Executor.
