title: How to pass rustc flags to cargo?
body: <p>I am trying to disable dead code warnings. I tried the following</p>
  
  <pre><code>cargo build -- -A dead_code
  </code></pre>
  
  <blockquote>
    <p>➜  rla git:(master) ✗ cargo build -- -A dead_code
    error: Invalid arguments.</p>
  </blockquote>
  
  <p>So I am wondering how would I pass rustc arguments to cargo?</p>
