<p>This acts effectively the same as an <a href="../event/struct.EventReader.html" title="struct bevy_ecs::event::EventReader"><code>EventReader</code></a>.</p>
<p>Note that this does not allow you to see which data existed before removal.
If you need this, you will need to track the component data value on your own,
using a regularly scheduled system that requests <code>Query&lt;(Entity, &amp;T), Changed&lt;T&gt;&gt;</code>
and stores the data somewhere safe to later cross-reference.</p>
<p>If you are using <code>bevy_ecs</code> as a standalone crate,
note that the <code>RemovedComponents</code> list will not be automatically cleared for you,

automatically called by <code>bevy_app::App::update</code> and <code>bevy_app::SubApp::update</code>.
