rustdoc: remove unused HTML class `sidebar-title`
Since 6a5f8b1aef1417d7dc85b5d0a229d2db1930eb7c, this class is no longer styled.
|
|
This allows you to open the help section in a new browser tab, which is a
pretty reasonable thing to want for a documentation page.

|
|
|
|
When this was added, the sidebar had a bit more complex style. It can be
removed, now.
|
|
This DOM cleanup changes the color of the triangle, from blue to black, but
since it's still a different color from the link it's next to, it should
still be noticeable.
|
|
Since 50f662e99ec372a3c9558876d4164e8665859217, there is no CSS or JS
targeting this class.

Since a7c25b29575c17434406b69773f8c2961af343b3 removed `in-band` from code
headers, the only remaining uses of the `in-band` class are:
https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/render/write_shared.rs#L520-L521

https://github.com/rust-lang/rust/blob/02cd79afb8080fce8c8ce35533c54d8ecf8f390e/src/librustdoc/html/render/mod.rs#L401-L402

Since all of these uses are nested below `h1.fqn`, we can get rid of it,
and the support code that was used for when `in-band` was part of item
rendering.

Fixes another regression caused by 8846c0853d8687fda0e5f23f6687b03b243980ee,
this time fixing the appearance of methods that have no docblock (we didn't
notice this one because libstd docs *always* have docblocks).
See how it looks at https://doc.rust-lang.org/nightly/nightly-rustc/rustdoc/clean/types/trait.AttributesExt.html

rustdoc: add method spacing to trait methods
More cleanup for 8846c0853d8687fda0e5f23f6687b03b243980ee, this time in trait layouts when things are collapsed.
This PR makes two changes to the appearance of trait pages:
* It adds the `method-toggle` class to method toggles on traits, making the DOM more consistent with type pages (which already have this class).
## Before
## After
* It adds a bottom margin to docblocks nested directly in the implementors list, giving it a similar appearance to if it was nested within a toggle.
## Before
## After

Instead, it gathers the extra info later, when it's actually requested.
|
|
* Remove the `float: right` fallback from the main header, which hasn't
been needed since IE11 support was dropped.
* Remove `in-band` from low-level headers, which hasn't been needed since
`.rightside` switched to `float: right` in
593d6d1cb15c55c88319470dabb40126c7b7f1e2
* Remove unreachable `.in-band > code, .in-band > .code-header` CSS, since
the `in-band` class was attached to the `code-header` itself, not nested
directly below it.
* Use `rem` instead of `em` for code header margins.
* This results in a slight change in spacing around impls and item-info,
but since it makes it more consistent with the way methods are presented,
it's probably fine.

Unify "all items" page's sidebar with other pages
Currently, the "all types" page's sidebar doesn't list the different categories of type available. This PR fixes it.

This class was originally added in 73b97c7e7c9cfac4dfa4804654b1db6ab687b589
to support hiding and showing the item, because `main.js` went through all
`docblock` elements in the DOM and added toggles to them.
https://github.com/rust-lang/rust/blob/73b97c7e7c9cfac4dfa4804654b1db6ab687b589/src/librustdoc/html/static/main.js#L1856-L1867
The `item-decl` is no longer auto-hidden since
c96f86de3026f864e78397aff9097e885f2f8fdf removed it.
`item-decl` used to be called `type-decl`: that name was changed in
8b7a2dd4626acf164e1ce8397878b3f5af83d585.
The `docblock` class is no longer used for implementing toggles, since
rustdoc switched to using `<details>` elements.

|
This reduces the amount of CSS, and makes these two pages more consistent
(which, necessarily, means changing them a bit).
|

As an example, this cuts down
<https://doc.rust-lang.org/nightly/nightly-rustc/src/rustc_middle/ty/mod.rs.html>
by about 11%.

Remove unneeded where whitespace
It fixes these two bugs:
It's a relic from a very old time (this commit: https://github.com/rust-lang/rust/commit/bfd01b7f40ae2cbfe9acbc1d10e79ffe16870df8).

Fix doc cfg on reexports
Fixes #83428.
The problem was that the newly inlined item cfg propagation was not working since its real parent is different than its current one.
For the implementation, I decided to put it directly into `CfgPropagation` instead of inside `inline.rs` because I thought it would be simpler to maintain and to not forget if new kind of items are added if it's all done in one place.

Optimize `Wtf8Buf::into_string` for the case where it contains UTF-8.
Add a `is_known_utf8` flag to `Wtf8Buf`, which tracks whether the
string is known to contain UTF-8. This is efficiently computed in many
common situations, such as when a `Wtf8Buf` is constructed from a `String`
or `&str`, or with `Wtf8Buf::from_wide` which is already doing UTF-16
decoding and already checking for surrogates.
This makes `OsString::into_string` O(1) rather than O(N) on Windows in
common cases.
And, it eliminates the need to scan through the string for surrogates in
`Args::next` and `Vars::next`, because the strings are already being
translated with `Wtf8Buf::from_wide`.
Many things on Windows construct `OsString`s with `Wtf8Buf::from_wide`,
such as `DirEntry::file_name` and `fs::read_link`, so with this patch,
users of those functions can subsequently call `.into_string()` without
paying for an extra scan through the string for surrogates.

rustdoc: strategic boxing to reduce the size of ItemKind and Type
The `Type` change redesigns `QPath` to box the entire data structure instead of boxing `self_type` and the `trait_`.
This reduces the size of several `ItemKind` variants, leaving `Impl` as the biggest variant. The `ItemKind` change boxes that variant's payload.

[rustdoc] Fix item info display
Fixes #100369.
The solution I came up with was simply to wrap the "text part" of the `item-info` into another span so that `flex` wouldn't mess with it.
Live demo is [here](https://rustdoc.crud.net/imperio/fix-item-info/foo/struct.ItemInfo.html).
