Correctly handle multiple-use #96

Closed porglezomp closed 7 years ago

It would be nice if line like std::io::{ would complete the same as std::io:: It would be even nicer if, for instance use std::rc::{Rc, would recommend everything that std::rc:: recommends, except it would omit Rc since it's already being used.

Hello Proglezomp! I definitely agree. Context based completions is just something I haven't got to with racer yet. This one should be pretty easy though so now that you've asked for it I might try doing this after I've finished if-let statements (which is what I'm doing at the moment). Thanks!

Technically, the following code is valid:

use std::fmt::{Formatter, Formatter as Fmtr};

I have no idea why someone would do this, but since it's allowed I'm reluctant to have rust hide things that have already been imported in the current use statement.

I was a little surprised to get this notification, but as far as I can tell the main issue here was resolved a while ago thanks to @yodalee, so I'm happy to have this issue closed.
