2016-04-12std: Stabilize APIs for the 1.9 releaseAlex Crichton-2/+1
This commit applies all stabilizations, renamings, and deprecations that the library team has decided on for the upcoming 1.9 release. All tracking issues have gone through a cycle-long "final comment period" and the specific APIs stabilized/deprecated are: Stable * `std::panic` * `std::panic::catch_unwind` (renamed from `recover`) * `std::panic::resume_unwind` (renamed from `propagate`) * `std::panic::AssertUnwindSafe` (renamed from `AssertRecoverSafe`) * `std::panic::UnwindSafe` (renamed from `RecoverSafe`) * `str::is_char_boundary` * `<*const T>::as_ref` * `<*mut T>::as_ref` * `<*mut T>::as_mut` * `AsciiExt::make_ascii_uppercase` * `AsciiExt::make_ascii_lowercase` * `char::decode_utf16` * `char::DecodeUtf16` * `char::DecodeUtf16Error` * `char::DecodeUtf16Error::unpaired_surrogate` * `BTreeSet::take` * `BTreeSet::replace` * `BTreeSet::get` * `HashSet::take` * `HashSet::replace` * `HashSet::get` * `OsString::with_capacity` * `OsString::clear` * `OsString::capacity` * `OsString::reserve` * `OsString::reserve_exact` * `OsStr::is_empty` * `OsStr::len` * `std::os::unix::thread` * `RawPthread` * `JoinHandleExt` * `JoinHandleExt::as_pthread_t` * `JoinHandleExt::into_pthread_t` * `HashSet::hasher` * `HashMap::hasher` * `CommandExt::exec` * `File::try_clone` * `SocketAddr::set_ip` * `SocketAddr::set_port` * `SocketAddrV4::set_ip` * `SocketAddrV4::set_port` * `SocketAddrV6::set_ip` * `SocketAddrV6::set_port` * `SocketAddrV6::set_flowinfo` * `SocketAddrV6::set_scope_id` * `<[T]>::copy_from_slice` * `ptr::read_volatile` * `ptr::write_volatile` * The `#[deprecated]` attribute * `OpenOptions::create_new` Deprecated * `std::raw::Slice` - use raw parts of `slice` module instead * `std::raw::Repr` - use raw parts of `slice` module instead * `str::char_range_at` - use slicing plus `chars()` plus `len_utf8` * `str::char_range_at_reverse` - use slicing plus `chars().rev()` plus `len_utf8` * `str::char_at` - use slicing plus `chars()` * `str::char_at_reverse` - use slicing plus `chars().rev()` * `str::slice_shift_char` - use `chars()` plus `Chars::as_str` * `CommandExt::session_leader` - use `before_exec` instead. Closes #27719 cc #27751 (deprecating the `Slice` bits) Closes #27754 Closes #27780 Closes #27809 Closes #27811 Closes #27830 Closes #28050 Closes #29453 Closes #29791 Closes #29935 Closes #30014 Closes #30752 Closes #31262 cc #31398 (still need to deal with `before_exec`) Closes #31405 Closes #31572 Closes #31755 Closes #31756

Originally added in 8fe9e4dff6d9d0fdd940835ae377edcb3754f8c1. Everything appears to build fine without the coercions, so they can presumably be removed.
2016-03-28style: Use `iter` for IntoIterator parameter namesKamal Marhubi-4/+4
This commit standardizes the codebase on `iter` for parameters with IntoIterator bounds. Previously about 40% of IntoIterator parameters were named `iterable`, with most of the rest being named `iter`. There was a single place where it was named `iterator`.

2016-03-12std: Clean out deprecated APIsAlex Crichton-20/+0
Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma.

The first time I read the docs for `insert()`, I thought it was saying it didn't update existing *values*, and I was confused. Reword the docs to make it clear that `insert()` does update values.

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

2016-01-19Add examples of the Entry API to the HashMap documentation.Nathan Kleyn-0/+29
Responding to [a thread of discussion on the Rust subreddit](https://www.reddit.com/r/rust/comments/3racik/mutable_lifetimes_are_too_long_when_matching_an/), it was identified that the presence of the Entry API is not duly publicised. This commit aims to add some reasonable examples of common usages of this API to the main example secion of the `HashMap` documentation. This is part of issue #29348.

2015-12-10std: Remove deprecated functionality from 1.5Alex Crichton-12/+11
This is a standard "clean out libstd" commit which removes all 1.5-and-before deprecated functionality as it's now all been deprecated for at least one entire cycle.
2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-8/+2
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

2015-08-12Remove all unstable deprecated functionalityAlex Crichton-14/+2
This commit removes all unstable and deprecated functions in the standard library. A release was recently cut (1.3) which makes this a good time for some spring cleaning of the deprecated functions.

2015-07-09Use vec![elt; n] where possibleUlrik Sverdrup-3/+3
The common pattern `iter::repeat(elt).take(n).collect::<Vec<_>>()` is exactly equivalent to `vec![elt; n]`, do this replacement in the whole tree. (Actually, vec![] is smart enough to only call clone n - 1 times, while the former solution would call clone n times, and this fact is virtually irrelevant in practice.)
