<p>If this trait yields to true (<span class="emphasis"><em><a class="link" href="has_triv_idm45507104705360.html" title="Struct template has_trivial_destructor_after_move">has_trivial_destructor_after_move</a> <T>::value == true</em></span>) means that if T is used as argument of a move construction/assignment, there is no need to call T's destructor. This optimization tipically is used to improve containers' performance.</p>
<p>By default this trait is true if the type has trivial destructor, every class should specialize this trait if it wants to improve performance when inserted in containers. </p>
