No. This is rust bindings to the native apple UI toolkits, UIKit and AppKit (on iOS and macos respectively). Using a library like this, your software will have a fully native look and feel. The result should be indistinguishable from the equivalent Swift or Obj-C app from the point of view of a user. Including all accessibility hooks, fully native widgets and things like that.

The downside is that code written against this api will not work on any other platform.

I’d take that downside over having to mix languages on each platform. UI toolkit Rust bindings for all the platforms I want to target would let me just write Rust instead of also having to write Swift, Java, JavaScript, etc.
