[Jonathan Reem]

This should be fixed by a cargo update now.

You have an old version of rustc with the old libcollections.

[Johannes Schickling]

Sorry, my bad.

[Jared McFarland]

@reem Thanks for fixing this so fast!

[Jonathan Reem]

@jaredonline Absolutely! I try to keep the response time low so it's actually practical to use these libraries.
