2015-02-18Stabilize std::borrowAaron Turon-10/+9
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 #22482: alexcrichton/cstr-changesAlex Crichton-10/+10
This commit is an implementation of [RFC 592][r592] and [RFC 840][r840]. These two RFCs tweak the behavior of `CString` and add a new `CStr` unsized slice type to the module. [r592]: https://github.com/rust-lang/rfcs/blob/master/text/0592-c-str-deref.md [r840]: https://github.com/rust-lang/rfcs/blob/master/text/0840-no-panic-in-c-string.md The new `CStr` type is only constructable via two methods: 1. By `deref`'ing from a `CString` 2. Unsafely via `CStr::from_ptr` The purpose of `CStr` is to be an unsized type which is a thin pointer to a `libc::c_char` (currently it is a fat pointer slice due to implementation limitations). Strings from C can be safely represented with a `CStr` and an appropriate lifetime as well. Consumers of `&CString` should now consume `&CStr` instead to allow producers to pass in C-originating strings instead of just Rust-allocated strings. A new constructor was added to `CString`, `new`, which takes `T: IntoBytes` instead of separate `from_slice` and `from_vec` methods (both have been deprecated in favor of `new`). The `new` method returns a `Result` instead of panicking. The error variant contains the relevant information about where the error happened and bytes (if present). Conversions are provided to the `io::Error` and `old_io::IoError` types via the `FromError` trait which translate to `InvalidInput`. This is a breaking change due to the modification of existing `#[unstable]` APIs and new deprecation, and more detailed information can be found in the two RFCs. Notable breakage includes: * All construction of `CString` now needs to use `new` and handle the outgoing `Result`. * Usage of `CString` as a byte slice now explicitly needs a `.as_bytes()` call. * The `as_slice*` methods have been removed in favor of just having the `as_bytes*` methods.

2015-02-18rollup merge of #22480: alexcrichton/hashv3Alex Crichton-6/+5
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/+342
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/
2015-02-18rollup merge of #22287: Ryman/purge_carthographersAlex Crichton-3/+3
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

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.
