2017-01-25std: Stabilize APIs for the 1.16.0 releaseAlex Crichton-4/+2
This commit applies the stabilization/deprecations of the 1.16.0 release, as tracked by the rust-lang/rust issue tracker and the final-comment-period tag. The following APIs were stabilized: * `VecDeque::truncate` * `VecDeque::resize` * `String::insert_str` * `Duration::checked_{add,sub,div,mul}` * `str::replacen` * `SocketAddr::is_ipv{4,6}` * `IpAddr::is_ipv{4,6}` * `str::repeat` * `Vec::dedup_by` * `Vec::dedup_by_key` * `Result::unwrap_or_default` * `<*const T>::wrapping_offset` * `<*mut T>::wrapping_offset` * `CommandExt::creation_flags` (on Windows) * `File::set_permissions` * `String::split_off` The following APIs were deprecated * `EnumSet` - replaced with other ecosystem abstractions, long since unstable Closes #27788 Closes #35553 Closes #35774 Closes #36436 Closes #36949 Closes #37079 Closes #37087 Closes #37516 Closes #37827 Closes #37916 Closes #37966 Closes #38080

2016-11-04core::ptr: Specify issue for ptr_wrapping_offset featureUlrik Sverdrup-2/+2
2016-10-27core::ptr: Add .wrapping_offset() methodsUlrik Sverdrup-0/+80
.wrapping_offset() exposes the arith_offset intrinsic in the core module. This is the first step in making it possible to stabilize the interface later. `arith_offset` is a useful tool for developing iterators for two reasons: 1. `arith_offset` is used by the slice's iterator, the most important iterator in libcore, and it is natural that Rust users need the same power available to implement similar iterators. 2. It is a good way to implement raw pointer iterations with step greater than one. The name seems to fit the style of methods like "wrapping_add".

2016-04-11std: Stabilize APIs for the 1.9 releaseAlex Crichton-27/+37
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.

2016-03-01Rollup merge of #31965 - miqid:doc, r=steveklabnikSteve Klabnik-1/+1
Hello. Quite a few of the links in the `core` module concerning redirection to additional primitive type documentation are broken. I noticed in #30214 that there seemed to be a consensus with linking across to `std` module documentation from the `core` module. This is what I've done with the `core` modules for primitive types. If the changes here are good to go forward with, I'll happily tend to adding more documentation links for the extension traits in the aforementioned issue if need be. r? @steveklabnik
2016-03-01Fix broken links for core primitivesMichael Huynh-1/+1
Redirects existing links for more details on primitive types in the `core` module to the ones that exist in the `std` module.

2015-10-16Add `Shared` pointer and have `{Arc, Rc}` use itAndrew Paseltiner-2/+67
This change has two consequences: 1. It makes `Arc<T>` and `Rc<T>` covariant in `T`. 2. It causes the compiler to reject code that was unsound with respect to dropck. See compile-fail/issue-29106.rs for an example of code that no longer compiles. Because of this, this is a [breaking-change]. Fixes #29037. Fixes #29106.

2015-08-15core: Fill out issues for unstable featuresAlex Crichton-9/+14
2015-08-12Remove all unstable deprecated functionalityAlex Crichton-21/+0
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.
2015-08-09Replace many uses of `mem::transmute` with more specific functionsTobias Bucher-7/+6
The replacements are functions that usually use a single `mem::transmute` in their body and restrict input and output via more concrete types than `T` and `U`. Worth noting are the `transmute` functions for slices and the `from_utf8*` family for mutable slices. Additionally, `mem::transmute` was often used for casting raw pointers, when you can already cast raw pointers just fine with `as`.
2015-07-29std: Remove the curious inner moduleAlex Crichton-1/+1
This isn't actually necessary any more with the advent of `$crate` and changes in the compiler to expand macros to `::core::$foo` in the context of a `#![no_std]` crate. The libcore inner module was also trimmed down a bit to the bare bones.
2015-07-27std: Deprecate a number of unstable featuresAlex Crichton-0/+3
Many of these have long since reached their stage of being obsolete, so this commit starts the removal process for all of them. The unstable features that were deprecated are: * cmp_partial * fs_time * hash_default * int_slice * iter_min_max * iter_reset_fuse * iter_to_vec * map_in_place * move_from * owned_ascii_ext * page_size * read_and_zero * scan_state * slice_chars * slice_position_elem * subslice_offset
