One of the things that use wgpu-rs is Iced[1], a cross-platform GUI Library inspired by the Elm Architecture.

Although the project started around May 2019 and is still highly experimental, it looks like they got a lot of progress made and things look promising! The interest seems incredible: they have 5.4K stars on GitHub (amazing for such a young project) and there are lots of impressive examples[2].

As someone who just learned about the project: hope this takes off!!! A lightweight, simple to use GUI toolkit that can run on the browser and desktop is really something developers desperately want.
