Taffy built in to my library?

[test3211234]

Hi, I have no idea how to do this. If I had widgets/views like Xilem, but with Taffy built in first-class instead of BoxConstraints (so we can use TaffyTree internally instead of traits externally), what would the layout and measure/compute_max_intrinsic function signatures look like and how would they be used (instead of the BoxConstraints that Masonry has)? Also, when Taffy is the main layout paradigm and there's no BoxConstraints, I don't see how I would make flex((...)) widget(s)/view(s) that take as arguments other widgets.
