1. A slice of parametrized type, say
BorrowedRef { ... Vector(Generic(T)) }, is rendered as
"<a href='primitive.slice.html'>&[T]</a>"
2. A slice of other types, say
BorrowedRef { ... Vector(int) }, is rendered as
"<a href='primitive.slice.html'>&[</a>
<a href='primitive.int.html'>int</a>
<a href='primitive.slice.html'>]</a>"
3. Other cases, say BorrowedRef { ... int }, are
rendered as same as before:
"&<a href='primitive.int.html'>int</a>"

states A tag must not enclose any "interactive contents"
which include A tags themselves.
This provides a way to pass `&[T]` to functions taking `&U` where `U` is
a `Vec<T>`. This is useful in many cases not covered by the Equiv trait
or methods like `find_with` on TreeMap.

Currently, the Guide says tuples "are only equivalent if the arity, types, and values are all identical", before presenting an example that uses `==` to compare two tuples whose arity and contained types match. This is misleading, because it implies that `==` can dynamically check whether two tuples have the same arity and contained types, whereas trying to do this would lead to a compiler error.
I tried to avoid destroying the flow of this section, but I'm not sure if I've been successful.
Because my '30 minute intro' was originally a blog post, the tone was a bit too light. It also was written a long time ago, and deserves a bit of a refresher for modern Rust. now that my work on the Guide is wrapping up, I want to give it a quick re-write as well.
This is not yet done, but I'm submitting it for feedback so far. I'd really like some comments on the ownership part in particular, which gets lower level than before, but is not strictly 100% accurate. Trying to strike a balance.
In general, I'm not sure I go into enough detail for those without systems experience, but am afraid of too much detail for those that do.

Adds a high-level discussion of "what collection should you use for what", as well as some general discussion of correct/efficient usage of the capacity, iterator, and entry APIs.
Still building docs to confirm this renders right and the examples are good, but the content can be reviewed now.
For example, this matcher: `fn $name:ident( $($param:ident : $pty:ty),* )` would fail when parsing `fn foo()`, because macro parser wouldn't realize that an ident cannot start with `)`.
This resolves#5902, and at least partially mitigates #9364 and #3232.
[Previously](e5da6a71a6), the `Any` trait was split into a private portion and an (empty) public portion, in order to hide the implementation strategy used for downcasting. However, the [new rules](e9ad12c0ca) for privacy forbid `AnyPrivate` from actually being private.
This patch thus reverts the introduction of `AnyPrivate`.
Although this is unlikely to break any real code, it removes a public trait and is therefore a:
[breaking-change]

This PR adds support in rustdoc for properly naming lifetimes in bounds, instead of just showing `'static` for everything. It also adds support for unboxed function sugar bounds, which were also previously rendered as `'static`.
Previously, external code might call `markdown::render()` without having
called `markdown::reset_headers()`, meaning the TLS key
`used_header_map` was unset. Now `markdown::render()` ensures that
`used_header_map` is set by calling `reset_headers` if necessary.
Fix#17736
