title: Can I use `std::path::Path`'s `strip_prefix` to replace a dynamic prefix?
body: <p>The reason I'm interested in doing this is because there's a part of my path which will remain constant but which I wish to remove along with all its parent pieces.</p>
  
  <p>So if we have say,</p>
  
  <pre><code>some/unknown/path/foo/bar/baz
  </code></pre>
  
  <p>I would like to return</p>
  
  <pre><code>bar/baz
  </code></pre>
  
  <p>But with the expectation that I only know <code>foo/...</code> directly proceeds the part of the path I care about.</p>
  
  <p>Perhaps <code>strip_prefix</code> is the wrong approach so if there's a better way of doing this I would certainly appreciate being pointed in that direction.</p>
