2015-02-18Stabilize std::borrowAaron Turon-2/+1
This commit stabilizes `std::borrow`, making the following modifications to catch up the API with language changes: * It renames `BorrowFrom` to `Borrow`, as was originally intended (but blocked for technical reasons), and reorders the parameters accordingly. * It moves the type parameter of `ToOwned` to an associated type. This is somewhat less flexible, in that each borrowed type must have a unique owned type, but leads to a significant simplification for `Cow`. Flexibility can be regained by using newtyped slices, which is advisable for other reasons anyway. * It removes the owned type parameter from `Cow`, making the type much less verbose. * Deprecates the `is_owned` and `is_borrowed` predicates in favor of direct matching. The above API changes are relatively minor; the basic functionality remains the same, and essentially the whole module is now marked `#[stable]`. [breaking-change]

2015-02-18rollup merge of #22480: alexcrichton/hashv3Alex Crichton-1/+1
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 [breaking-change]
2015-02-18rollup merge of #22452: nikomatsakis/issue-22040-18956-SelfAlex Crichton-0/+131
The big change here is that we update the object-safety rules to prohibit references to `Self` in the supertrait listing. See #22040 for the motivation. The other change is to handle the interaction of defaults that reference `Self` and object types (where `Self` is erased). We force users to give an explicit type in that scenario. r? @aturon
2015-02-18rollup merge of #22436: nikomatsakis/issue-22246-bound-lifetimes-of-assoc-typesAlex Crichton-0/+273
Take 2. This PR includes a bunch of refactoring that was part of an experimental branch implementing [implied bounds]. That particular idea isn't ready to go yet, but the refactoring proved useful for fixing #22246. The implied bounds branch also exposed #22110 so a simple fix for that is included here. I still think some more refactoring would be a good idea here -- in particular I think most of the code in wf.rs is kind of duplicating the logic in implicator and should go, but I decided to post this PR and call it a day before diving into that. I'll write a bit more details about the solutions I adopted in the various bugs. I patched the two issues I was concerned about, which was the handling of supertraits and HRTB (the latter turned out to be fine, so I added a comment explaining why.) r? @pnkfelix (for now, anyway) cc @aturon [implied bounds]: http://smallcultfollowing.com/babysteps/blog/2014/07/06/implied-bounds/

After making `rustc` fail on errors at a stop point, like `-Z parse-only`, in #22117, the files in this PR also fail during the parse stage and should be moved as well. Sorry for spliting this move up in two PRs.

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.
2015-02-18std: Stabilize the `hash` moduleAlex Crichton-1/+1
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.

2015-02-17Fallout from stabilizationAaron Turon-40/+40
2015-02-17rollup merge of #22024: alexcrichton/asciiAlex Crichton-0/+5
* Move the type parameter on the `AsciiExt` trait to an associated type named `Owned`. * Move `ascii::escape_default` to using an iterator. This is a breaking change due to the removal of the type parameter on the `AsciiExt` trait as well as the modifications to the `escape_default` function to returning an iterator. Manual implementations of `AsciiExt` (or `AsciiExt` bounds) should be adjusted to remove the type parameter and using the new `escape_default` should be relatively straightforward. [breaking-change]

2015-02-17std: Rename io/path features with old_ prefixAlex Crichton-9/+8
This commit renames the features for the `std::old_io` and `std::old_path` modules to `old_io` and `old_path` to help facilitate migration to the new APIs. This is a breaking change as crates which mention the old feature names now need to be renamed to use the new feature names. [breaking-change]

Previously an implementation of a stable trait allows implementations of unstable methods. This updates the stability pass to ensure that all items of an impl block of a trait are indeed stable on the trait itself.

Pass features along during expansion Use the set of passed features to detect uses of feature-gated macros without the corresponding feature enabled. Fix #22234. ---- Also, the framework this add (passing along a reference to the features in the expansion context) is a necessary precursor for landing a properly feature-gated desugaring-based overloaded-`box` and placement-`in` (#22181). ---- This is fixing a bug, but since there might be code out there that is unknowingly taking advantage of that bug, I feel obligated to mark this as a: [breaking-change]
