This PR:
- makes rustdoc colour trait methods like other functions in search results;
- makes rustdoc display `extern crate` statements with the new `as` syntax instead of the old `=` syntax;
- changes rustdoc to list constants and statics in a way that is more similar to functions and modules and show their full definition and documentation on their own page, fixing #19046:
Closes https://github.com/rust-lang/rust/issues/19077
I would appreciate any guidance on how to write a test for this. I saw some examples in `test/pretty`, but there are different ways to test... With or without `.pp` files, with a `pp-exact` comment, etc.
This breaks code like
```
let t = (42i, 42i);
... t.0::<int> ...;
```
Change this code to not contain an unused type parameter. For example:
```
let t = (42i, 42i);
... t.0 ...;
```

Catch a missed triple-slash in the docs for `std::os::args()`. Passes `make check`. (I've also eyeballed the rest of `libstd` with the aid of some funky regexes and haven't found anything similar.)
This is an initial API stabilization pass for `std::ascii`. Aside from
some renaming to match conversion conventions, and deprecations in favor
of using iterators directly, almost nothing is changed here. However,
the static case conversion tables that were previously public are now private.
The stabilization of the (rather large!) set of extension traits is left
to a follow-up pass, because we hope to land some more general machinery
that will provide the same functionality without custom traits.

These functions allow you to see how many weak and strong references
there are to an `Arc`, `Rc`, or an `rc::Weak`. Due to the design of
`Arc` it is not possible to get the number of weak references of an
arbitrary `arc::Weak`. Look in `arc.rs` for a more in-depth explanation.
On `arc::Arc` and `arc::Weak` these operations are wait-free and atomic.
This sort of information is useful for creating dynamically cleared caches for use in OS development, for example holding pages of files in memory until the address space is needed for something else.
This is a collection of misc issues I've run into while adding bindir & libdir support that aren't really bindir & libdir specific.
While I continue to fiddle with bindir and libdir bugs, I figured these might be useful for others to have merged.
The reason given didn't make any sense when I read it when reading through the docs. I think this is more clear. Please let me know it is also more correct.
The impl for [T] also works as impl for slices in general.
By generalizing the impl of StrVector for Vec<Str> to that for
AsSlice<Str>, it becomes much more generic.
Once Iterable is implemented, we will prefer it to AsSlice.
But the with_capacity() part might become tricky.

This commit makes `Cow` more usable by allowing it to be applied to
unsized types (as was intended) and providing some basic `ToOwned`
implementations on slice types. It also corrects the documentation for
`Cow` to no longer mention `DerefMut`, and adds an example.
Closes#19123
This commit is an implementation of [RFC 240][rfc] when applied to the standard
library. It primarily deprecates the entirety of `string::raw`, `vec::raw`,
`slice::raw`, and `str::raw` in favor of associated functions, methods, and
other free functions. The detailed renaming is:
* slice::raw::buf_as_slice => slice::from_raw_buf
* slice::raw::mut_buf_as_slice => slice::from_raw_mut_buf
* slice::shift_ptr => deprecated with no replacement
* slice::pop_ptr => deprecated with no replacement
* str::raw::from_utf8 => str::from_utf8_unchecked
* str::raw::c_str_to_static_slice => str::from_c_str
* str::raw::slice_bytes => deprecated for slice_unchecked (slight semantic diff)
* str::raw::slice_unchecked => str.slice_unchecked
* string::raw::from_parts => String::from_raw_parts
* string::raw::from_buf_len => String::from_raw_buf_len
* string::raw::from_buf => String::from_raw_buf
* string::raw::from_utf8 => String::from_utf8_unchecked
* vec::raw::from_buf => Vec::from_raw_buf
All previous functions exist in their `#[deprecated]` form, and the deprecation
messages indicate how to migrate to the newer variants.
