2016-01-26std: Stabilize custom hasher support in HashMapAlex Crichton-41/+54
This commit implements the stabilization of the custom hasher support intended for 1.7 but left out due to some last-minute questions that needed some decisions. A summary of the actions done in this PR are: Stable * `std::hash::BuildHasher` * `BuildHasher::Hasher` * `BuildHasher::build_hasher` * `std::hash::BuildHasherDefault` * `HashMap::with_hasher` * `HashMap::with_capacity_and_hasher` * `HashSet::with_hasher` * `HashSet::with_capacity_and_hasher` * `std::collections::hash_map::RandomState` * `RandomState::new` Deprecated * `std::collections::hash_state` * `std::collections::hash_state::HashState` - this trait was also moved into `std::hash` with a reexport here to ensure that we can have a blanket impl to prevent immediate breakage on nightly. Note that this is unstable in both location. * `HashMap::with_hash_state` - renamed * `HashMap::with_capacity_and_hash_state` - renamed * `HashSet::with_hash_state` - renamed * `HashSet::with_capacity_and_hash_state` - renamed Closes #27713

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-3/+1
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968

2015-11-16Fix docs for HashSet::insertSebastian Hahn-4/+1
insert() returns bool, but it was wrongly stated that if the set had the key already present, that key would be returned (this was probably copied from the HashMap docs). Also remove a reference to the module-level documentation, which doesn't make sense as it doesn't give any more context.

2015-04-21rollup merge of #24541: alexcrichton/issue-24538Alex Crichton-29/+24
This is an implementation of [RFC 1030][rfc] which adds these traits to the prelude and additionally removes all inherent `into_iter` methods on collections in favor of the trait implementation (which is now accessible by default). [rfc]: https://github.com/rust-lang/rfcs/pull/1030 This is technically a breaking change due to the prelude additions and removal of inherent methods, but it is expected that essentially no code breaks in practice.

2015-03-31std: Remove #[old_orphan_check] from PartialEqAlex Crichton-1/+1
This is a deprecated attribute that is slated for removal, and it also affects all implementors of the trait. This commit removes the attribute and fixes up implementors accordingly. The primary implementation which was lost was the ability to compare `&[T]` and `Vec<T>` (in that order). This change also modifies the `assert_eq!` macro to not consider both directions of equality, only the one given in the left/right forms to the macro. This modification is motivated due to the fact that `&[T] == Vec<T>` no longer compiles, causing hundreds of errors in unit tests in the standard library (and likely throughout the community as well). cc #19470 [breaking-change]

2015-02-18Stabilize std::borrowAaron Turon-3/+3
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]

2015-02-18make FromIterator use IntoIteratorAlexis-1/+2
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. [breaking-change]

2015-02-18std: Stabilize the `hash` moduleAlex Crichton-73/+48
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]

2015-02-17std: Stabilize the IntoIterator traitAlex Crichton-0/+2
Now that the necessary associated types exist for the `IntoIterator` trait this commit stabilizes the trait as-is as well as all existing implementations.
2015-02-17Rollup merge of #22313 - japaric:iter, r=aturonManish Goregaokar-0/+32
`IntoIterator` now has an extra associated item: ``` rust trait IntoIterator { type Item; type IntoIter: Iterator<Self=Self::Item>; } ``` This lets you bind the iterator \"`Item`\" directly when writing generic functions: ``` rust // hypothetical change, not included in this PR impl Extend<T> for Vec<T> { // you can now write fn extend<I>(&mut self, it: I) where I: IntoIterator<Item=T> { .. } // instead of fn extend<I: IntoIterator>(&mut self, it: I) where I::IntoIter: Iterator<Item=T> { .. } } ``` The downside is that now you have to write an extra associated type in your `IntoIterator` implementations: ``` diff impl<T> IntoIterator for Vec<T> { + type Item = T; type IntoIter = IntoIter<T>; fn into_iter(self) -> IntoIter<T> { .. } } ``` Because this breaks all downstream implementations of `IntoIterator`, this is a [breaking-change] --- r? @aturon
