> Why does the rust documentation still suck?

Thats a bit harsh. Yes, the documentation might be (is) a bit hard to read in a sense that its hard to _find_ something from it, but otherwise I've found if quite complete (when it comes to the standard library). Most (if not all) of your points are about the readability of the rendered documentation and not the documentation (content) it self.

Yes, almost all my complaints about rust doc is in formatting, sectioning, and grouping. The content is good.

But those display issues make it unusable unless you know what you are already looking for.
