Changes .or() so that it can return a Result with a different E type
than the one it is called on.
Essentially:
fn or(self, res: Result<T, E>) -> Result<T, E>
becomes
fn or<F>(self, res: Result<T, F>) -> Result<T, F>
This brings `or` in line with the existing `and` & `or_else`
This is a
[breaking-change]
Due to some code needing additional type annotations.

Makes Rust less amusing by fixing [#22745](https://github.com/rust-lang/rust/issues/22745)

This is not a complete implementation of the RFC:
- only existing methods got updated, no new ones added
- doc comments are not extensive enough yet
- optimizations got lost and need to be reimplemented
See https://github.com/rust-lang/rfcs/pull/528
Technically a
[breaking-change]
|
|
|
|
Added a few bugfixes and additional testcases
|
|
This allows to match with a `&String` or `&&str`, for example.
|
|
Made the family of Split iterators use the Pattern API
Renamed the Matcher traits into Searcher

This commit is an implementation of [RFC 823][rfc] which is another pass over
the `std::hash` module for stabilization. The contents of the module were not
entirely marked stable, but some portions which remained quite similar to the
previous incarnation are now marked `#[stable]`. Specifically:
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0823-hash-simplification.md
* `std::hash` is now stable (the name)
* `Hash` is now stable
* `Hash::hash` is now stable
* `Hasher` is now stable
* `SipHasher` is now stable
* `SipHasher::new` and `new_with_keys` are now stable
* `Hasher for SipHasher` is now stable
* Many `Hash` implementations are now stable
All other portions of the `hash` module remain `#[unstable]` as they are less
commonly used and were recently redesigned.
This commit is a breaking change due to the modifications to the `std::hash` API
and more details can be found on the [RFC][rfc].
Closes #22467

This overlaps with #22276 (I left make check running overnight) but covers a number of additional cases and has a few rewrites where the clones are not even necessary.
This also implements `RandomAccessIterator` for `iter::Cloned`
cc @steveklabnik, you may want to glance at this before #22281 gets the bors treatment

here. Some of this may have been poorly rebased, though I tried to be
careful and preserve the spirit of the test.

and also follows the API of `NonZero` a bit more closely. More to do
here I think (including perhaps a new name).

Port `core::ptr::Unique` to have `PhantomData`. Add `PhantomData` to
`TypedArena` and `Vec` as well.
As a drive-by, switch `ptr::Unique` from a tuple-struct to a struct
with fields.

This is to allow for use cases like sending a raw pointer slice across thread boundaries.

When self.start > self.end, these iterators simply return None,
so we adjust the size_hint to just return zero in this case.
Certain optimizations can be implemented in and outside libstd if we
know we can trust the size_hint for all inputs to for example
Range<usize>.
This corrects the ExactSizeIterator implementations, which IMO were
unsound and incorrect previously, since they allowed a range like (2..1)
to return a size_hint of -1us in when debug assertions are turned off.

Use [`rand`](https://crates.io/crates/rand) and [`derive_rand`](https://crates.io/crates/derive_rand) from crates.io.

Use the crates.io crate `rand` (version 0.1 should be a drop in
replacement for `std::rand`) and `rand_macros` (`#[derive_Rand]` should
be a drop-in replacement).

The existence of these two functions is at odds with our current [error
conventions][conventions] which recommend that panicking and `Result`-like
variants should not be provided together.
[conventions]: https://github.com/rust-lang/rfcs/blob/master/text/0236-error-conventions.md#do-not-provide-both-result-and-fail-variants
This commit adds a new `borrow_state` function returning a `BorrowState` enum to
`RefCell` which serves as a replacemnt for the `try_borrow` and `try_borrow_mut`
functions.

Also some tidying up of a bunch of crate attributes
