Add settings page to Rustdoc for long-term configuration

[Gankra]

Would use localStorage to maintain state between pages.

Ideas:

• Collapse permanency settings from rustdoc: make collapsing permanent #17126. Two independent check-boxes:
  • Always collapse function-level docs
  • Always collapse top-level docs
• Hide deprecated functions
• Hide unsafe functions
• Only show stable functions

I have used localStorage extensively for the same kind of thing in a project of mine. It's a little bit messy, but maybe it can help :)

I've also used localStorage a fair amount (granted, 3 years ago): https://github.com/WhatPumpkin/Sburb/blob/master/src/serialization.js#L69-L158

Honestly the main thing that prevented me from ever going at this was building the menus and stuff. UI designers wanted :)

I suppose I could make stuff persist without giving any way to configure...

I have a couple of ideas:

1. Add one more keyboard shortcut. Like the current ? another keyboard shortcut could open an options panel with some check-boxes.
2. Reduce the width of the search bar a little bit and place an cog icon on the right of it, that opens a panel when clicked.

Another thing I would add to that settings panel is the a toggle for serif / sans-serif font

Like a mentioned in a post on Rust internals, I think it's worth having a centralized place for all the design decisions where designers would be invited to post ideas and mock-ups

Yes please. Collapsing all of the methods alone would be a huge improvement.

Javadoc has a separate method summary table + detailed documentation further down. Since rustdoc does not have that it's necessary to collapse the details every time to get an overview.

I usually have a rough idea what I want and just need to find that one method out of a myriad, so I would prefer the methods to be collapsed by default.
