This changes the parsing of the language string
in code examples so that unrecognized examples
are not considered Rust code. This was, for example,
the case when a code example was marked `sh` for shell
code.
This relieves authors of having to mark those samples
as `notrust`.
Also adds recognition of the positive marker `rust`.
By default, unmarked examples are still considered rust.
If any rust-specific tags are seen, code is considered
rust unless marked as "notrust".
Adds test cases for the detection logic.
This completes the last stage of the renaming of the comparison hierarchy of
traits. This change renames TotalEq to Eq and TotalOrd to Ord.
In the future the new Eq/Ord will be filled out with their appropriate methods,
but for now this change is purely a renaming change.
This continues the work of #12517, continuing the work in #14534. This patch accomplishes the final rename of `TotalEq` to `TotalOrd`. I wanted to get this patch landed ASAP so we don't have to deal much with "where did `Eq` and `Ord` go?"
I have yet to do another pruning pass over the compiler to change all usage of `PartialEq` to `Eq` where appropriate. I will do this soon as well.

Cross crate links can target items which are not rendered in the documentation.
If the item is reexported at a higher level, the destination of the link (a
concatenation of the fully qualified name) may actually lead to nowhere. This
fixes this problem by altering rustdoc to emit pages which redirect to the local
copy of the reexported structure.

There is currently no way to query all impls for a type from an external crate,
and with primitive types in play this is also quite difficult. Instead of
filtering, just suck in all impls from upstream crates into the local AST, and
have them get stripped later.
This will allow population of all implementations of traits for primitive types,
as well as filling in some corner cases with inlining documentation in other
cases.
This commit adds support in rustdoc to recognize the `#[doc(primitive = "foo")]`
attribute. This attribute indicates that the current module is the "owner" of
the primitive type `foo`. For rustdoc, this means that the doc-comment for the
module is the doc-comment for the primitive type, plus a signal to all
downstream crates that hyperlinks for primitive types will be directed at the
crate containing the `#[doc]` directive.
Additionally, rustdoc will favor crates closest to the one being documented
which "implements the primitive type". For example, documentation of libcore
links to libcore for primitive types, but documentation for libstd and beyond
all links to libstd for primitive types.
This change involves no compiler modifications, it is purely a rustdoc change.
The landing pages for the primitive types primarily serve to show a list of
implemented traits for the primitive type itself.
The primitive types documented includes both strings and slices in a semi-ad-hoc
way, but in a way that should provide at least somewhat meaningful
documentation.
Closes#14474
When inlining documentation across crates, primitive implementors of traits were
not shown. This commit tweaks the infrastructure to treat primitive and
Path-like impls the same way, displaying all implementors everywhere.

Instead of one giant function, this breaks it up into several smaller functions
which have explicit dependencies among one another.
There are no code changes as a result of this commit.
Renamed `owned_box` to `on_the_heap` to use a consistent
naming across the tutorial and the life time guide.
Also it makes the example easier to grasp.

By dropping the intermediate vector that holds the relevant candidates
including duplicates and directly building the vector that has the
duplicates removed we can eliminate quite a few allocations. This
reduces the times for type checking by 5-10% (measured with libstd,
libsyntax and librustc).

Adds a platform-specific function, `split_paths` to the `os` module. This
function can be used to parse PATH-like environment variables according to
local platform conventions.
Closes#14352.
