# [Live Build Here](http://cg.scs.carleton.ca/~abeinges/doc/std/vec/struct.Vec.html)

This is something that's been bothering me, and I've seen some people mention in IRC before. The docs are *great* if you want a full in-depth look at an API, but *awful* if you want to scan them. This provides the ability to toggle complexity freely. Interacts perfectly well with noscript, since the static page is effectively unchanged. Collapsing is just hiding divs with css.

I'm not much of a designer, so design input welcome on the actual UX for toggling.

The actual javascript is *a bit* brittle to layout changes, but it always will be without adding lots of extra junk to the actual markup, which didn't seem worth it.

rustdoc: Add generator meta tag to API docs

This is consistent with the meta tag in Markdown docs run through
rustdoc.
core: add a reverse method to Ordering.

This flips the comparison and is designed to be used when sorting etc.
