* Added links where possible (limited because of facading)
* Changed references to methods from `foo()` to `foo` in module docs
* Changed references to methods from `HashMap::foo` to just `foo` in
top-level docs for `HashMap` and the `default` doc for `DefaultHasher`
* Various small other fixes
|

This greatly improves consistency.

Advertise Vec in LinkedList docs
r? @steveklabnik
Hi! We already [advise](https://doc.rust-lang.org/std/collections/#use-a-linkedlist-when) to use `Vec` instead of `LinkedList` in the top-level collections documentation. But I think it may be missed by someone who just directly finds `LinkedList`.
What do you feel about advertising `Vec` directly in `LinkedList` docs as well?

Implement 1581 (FusedIterator)
* [ ] Implement on patterns. See https://github.com/rust-lang/rust/issues/27721#issuecomment-239638642.
* [ ] Handle OS Iterators. A bunch of iterators (`Args`, `Env`, etc.) in libstd wrap platform specific iterators. The current ones all appear to be well-behaved but can we assume that future ones will be?
* [ ] Does someone want to audit this? On first glance, all of the iterators on which I implemented `FusedIterator` appear to be well-behaved but there are a *lot* of them so a second pair of eyes would be nice.
* I haven't touched rustc internal iterators (or the internal rand) because rustc doesn't actually call `fuse()`.
* `FusedIterator` can't be implemented on `std::io::{Bytes, Chars}`.
Closes: #35602 (Tracking Issue)
Implements: rust-lang/rfcs#1581

This trait can be used to avoid the overhead of a fuse wrapper when an iterator
is already well-behaved.

Add `contains` to `VecDeque` and `LinkedList` (+ tests)
This implements [RFC 1552](https://github.com/rust-lang/rfcs/blob/master/text/1552-contains-method-for-various-collections.md). Tracking issue: #32630
Sorry for the late response. This is my first contribution, so please tell me if anything isn't optimal!

first round of removal of integer suffixes
|
|
Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that
are deprecated in the 1.8 release are sticking around for the rest of this
cycle.
Some notable changes are:
* The `dynamic_lib` module was moved into `rustc_back` as the compiler still
relies on a few bits and pieces.
* The `DebugTuple` formatter now special-cases an empty struct name with only
one field to append a trailing comma.

Remove `stable` stability annotations from inherent impls
|
|
I needed it in `RawVec`, `Vec`, and `TypedArena` for `rustc` to
bootstrap; but of course that alone was not sufficient for `make
check`.
Later I added `unsafe_destructor_blind_to_params` to collections, in
particular `LinkedList` and `RawTable` (the backing representation for
`HashMap` and `HashSet`), to get the regression tests exercising
cyclic structure from PR #27185 building.
----
Note that the feature is `dropck_parametricity` (which is not the same
as the attribute's name). We will almost certainly vary our strategy
here in the future, so it makes some sense to have a not-as-ugly name
for the feature gate. (The attribute name was deliberately selected to
be ugly looking.)

This does cause some breakage due to deficiencies in resolve -
`path::Components` is both an `Iterator` and implements `Eq`, `Ord`,
etc. If one calls e.g. `partial_cmp` on a `Components` and passes a
`&Components` intending to target the `PartialOrd` impl, the compiler
will select the `partial_cmp` from `Iterator` and then error out. I
doubt anyone will run into breakage from `Components` specifically, but
we should see if there are third party types that will run into issues.
`iter::order::equals` wasn't moved to `Iterator` since it's exactly the
same as `iter::order::eq` but with an `Eq` instead of `PartialEq` bound,
which doensn't seem very useful.
I also updated `le`, `gt`, etc to use `partial_cmp` which lets us drop
the extra `PartialEq` bound.

This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of
the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The
`#![no_std]` attribute now injects `extern crate core` at the top of the crate
as well as the libcore prelude into all modules (in the same manner as the
standard library's prelude). The `#![no_core]` attribute disables both std and
core injection.

This commit also deprecates the `as_string` and `as_slice` free functions in the
`string` and `vec` modules.

I had to use `impl<'a, V: Copy> Extend<(usize, &'a V)> for VecMap<V>` instead of `impl<'a, V: Copy> Extend<(&'a usize, &'a V)> for VecMap<V>` as that's what is needed for doing
```rust
let mut a = VecMap::new();
let b = VecMap::new();
b.insert(1, "foo");
a.extend(&b)
```
I can squash the commits after review.
