Add sidebar sections to Table of Content

[jakubdabek]

When I'm on a type's doc page and it has a lot of methods, it's tedious to scroll the sidebar to Trait implementations or other sections (could also ctrl+F, but that's also not that convenient).

It would be useful to add the links to these sections to the Table of Content widget.

Hi, @jakubdabek. The left sidebar has a Trait implementations section, do you think it's inconvenient?

Yes, it's inconvenient to scroll the left sidebar to this section, especially on types with a lot of inherent methods, like Vec, slice, Result etc.
