 with <code>this</code> and <code>const failure_type&lt;T&gt; &amp;</code>.</p>

<p><em>Requires</em>: <code>predicate::enable_make_exception_ptr_compatible_conversion&lt;void, T, void&gt;</code> is true, or <code>T</code> is <code>void</code>.</p>

<p><em>Complexity</em>: Same as for the <code>error_type</code> constructor which accepts <code>T</code>
