title: Can I add a dependent crate that is a subdirectory in a git repository?
body: <p>I want to use an EDN parser but it is inside <a href="https://github.com/mozilla/mentat" rel="noreferrer">https://github.com/mozilla/mentat</a>. <a href="https://github.com/mozilla/mentat/tree/master/edn" rel="noreferrer">https://github.com/mozilla/mentat/tree/master/edn</a> has its own Cargo.toml.</p>
  
  <p>I tried this:</p>
  
  <pre><code>[dependencies]
  edn = { git = "https://github.com/mozilla/mentat/tree/master/edn" }
  </code></pre>
  
  <p>But it doesn't work.</p>
  
  <p>Is it possible to add dependency to this crate inside the mentat repository?</p>
