Third time's a charm?
Raph Levien make another stab at a UI framework for #rust.
His text editor PoC #xi was very interesting, but is now on hiatus. The next project is the #druid UI framework and as far as I know it is still going.
Now there is a refreshed idea named #xilem and it promises to solve a lot of the issues and be better suited for #rust.

Hopefully some fruits are born from this research that will allow great things for UIs in #rustlang
