Laravel Illuminate\Validation\Rule not found
<p>I am trying to submit a form and validate the content.
In one of the requests I need to make a special rule.
I followed the documentation and it says to use unique and declare a Rule.</p>

<pre><code>use Illuminate\Validation\Rule;

Validator::make($data, [
'email' =&gt; [
    'required',
    Rule::unique('users')-&gt;ignore($user-&gt;id),
],
]);
</code></pre>

<p>I am trying with the example from the documentation, but all I get it this error:</p>

<pre><code>Class 'Illuminate\Validation\Rule' not found
</code></pre>

<p>I declared the line</p>

<pre><code>use Illuminate\Validation\Rule;
</code></pre>

<p>In my controller, but the error is still there.</p>
