<p dir="auto">When I read the documentation of the rust standard library from google, I don't know to which version of rust it refers. It could be great to have a footer with the version and a text which appear when we put our cursor on the rust logo which display the version of the library this doc refer to.</p>
<p dir="auto">That mean improving the documentation compilator of rust.</p>
<p dir="auto">I recently was using a library whose online documentation was out of date. One of the method signatures had changed and that wasn't reflected in the documentation. I checked the source code of the project to confirm that the signature had changed, but it also would have been nice to see on the documentation page that the version I was using didn't match up to the documentation version.</p>
