a994a99ec4 Always prefer where-clauses over impls in trait selection. Fixes #22110. 2015-02-18 15:23:34 -05:00

2939e483fd Extend the implicator so it produces general obligations and also so 
that it produces "outlives" relations for associated types. Add
several tests relating to #22246.

48c70d6863 Replace assert_no_late_bound_regions with 
`no_late_bound_regions().unwrap()`, which allows us to write code that
doesn't necessarily *fail* when there are higher-ranked trait bounds.

811c48fe22 For now, accept the i, u, is, and us suffixes, but warn when 
they are used without a feature-gate. This is both kinder to existing
code and should make it easier to land this PR, since we don't
have to catch EVERY SINGLE SUFFIX.

66613e26b9 make FromIterator use IntoIterator 
This breaks all implementors of FromIterator, as they must now accept IntoIterator instead of Iterator. The fix for this is generally trivial (change the bound, and maybe call into_iter() on the argument to get the old argument).

Users of FromIterator should be unaffected because Iterators are IntoIterator.

5fa9de16df Implement RFC 580 
This commit implements RFC 580 by renaming:

* DList -> LinkedList
* Bitv -> BitVec
* BitvSet -> BitSet
* RingBuf -> VecDeque

More details are in [the
RFC](https://github.com/rust-lang/rfcs/pull/580)

f83e23ad7c std: Stabilize the hash module 
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

801bc48939 Rewrite Unique<T> so that it is covariant in T, implies NonZero and ownership, 
and also follows the API of `NonZero` a bit more closely. More to do
here I think (including perhaps a new name).
