title: How to check standard library documentation offline?
body: <p>I found <code>rustdoc</code> command and I kind of expected it to work like <code>pydoc</code>. Unfortunately, <code>rustdoc std::io:stdin</code> doesn't do what I'd like it to. Is there a way to view standard library documentation in an offline form, either via command line or some kind of built in web server, like Python's <code>pydoc</code> allows?</p>
