Play 2.5 What is akka.stream.Materializer useful for?
<p>I started to use Play 2.5 recently, and I was wondering what the purpose of doing the following was: </p>

<pre><code>@Inject() (implicit val mat: Materializer)
</code></pre>

<p>I had several pieces of code not working and solved that issue thanks to this, but I still don't see what the materializer is doing.</p>

<p>Thanks</p>
