“closest” instance of the type. For example, if an <code>App</code> stores a <code>u32</code>, a nested <code>Scope</code>
also stores a <code>u32</code>, and the delegated request handler falls within that <code>Scope</code>, then
calling <code>.app_data::&lt;u32&gt;()</code> on an <code>HttpRequest</code> within that handler will return the
<code>Scope</code>s instance. However, using the same router set up and a request that does not get
captured by the <code>Scope</code>, <code>.app_data::&lt;u32&gt;()</code> would return the <code>App</code>s instance.</p>
<p>If the state was stored using the <a href="web/struct.Data.html" title="struct actix_web::web::Data"><code>Data</code></a> wrapper, then it must also be retrieved using
