Simplified foreign type rendering by switching from tables to flexbox. Also, removed some seemingly extraneous elements like “ghost” spans. Reduces element count on std::iter::Iterator by 30%.
If a match arm does not include all fields in a structure and a later pattern includes a field that is an array, we will attempt to use the array type from the prior arm. When calculating the field type, treat a array of an unknown size as a TyErr.
…umeGomez Simplify foreign type rendering. Simplified foreign type rendering by switching from tables to flexbox. Also, removed some seemingly extraneous elements like “ghost” spans. Reduces element count on the `std::iter::Iterator` page by 30%. On my laptop it drops Iterator page load time from ~15s to ~10s. Frame times during scrolling are a hair lower too. Known visual changes (happy to tweak based on feedback): * The main `impl ...` headers are now getting the default, larger, h3 font size. This was an accident, but I liked how it turned out so I didn't fix it. * There's a hair less vertical spacing between the end of a where block and the start of the next fn. Now, all spacing is consistent. I think this looks a bit worse. I may tweak vertical spacing more here or in a follow-up that cleans up vertical spacing more broadly. * "[src]" links are all sized at 17px. A few were 19px in the original. I haven't yet done heavy cross-browser or cross-crate testing. I was hoping to get a quick thumbs up or thumbs down here at this first draft, then if this is on the right track I'll spend some time on that testing. TODO: - [x] Test on Chrome - [x] Test on Firefox - [ ] ~~Test on UC Android~~ - [x] Test on Edge - [x] Test on iOS safari - [x] Test on desktop safari - [x] Update automated tests - [x] Increase vertical margin - [x] Fix "Important traits for" hover overlap - [x] Wait for rust-lang#55798 to land & merge it

Fix rust-lang#57279.
librustc_mir: Fix ICE with slice patterns If a match arm does not include all fields in a structure and a later pattern includes a field that is an array, we will attempt to use the array type from the prior arm. When calculating the field type, treat a array of an unknown size as a `TyErr`. Fixes: rust-lang#57472
