2015-10-25std: Stabilize library APIs for 1.5Alex Crichton-0/+2
This commit stabilizes and deprecates library APIs whose FCP has closed in the last cycle, specifically: Stabilized APIs: * `fs::canonicalize` * `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists, is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait. * `Formatter::fill` * `Formatter::width` * `Formatter::precision` * `Formatter::sign_plus` * `Formatter::sign_minus` * `Formatter::alternate` * `Formatter::sign_aware_zero_pad` * `string::ParseError` * `Utf8Error::valid_up_to` * `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}` * `<[T]>::split_{first,last}{,_mut}` * `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated but will be once 1.5 is released. * `str::{R,}MatchIndices` * `str::{r,}match_indices` * `char::from_u32_unchecked` * `VecDeque::insert` * `VecDeque::shrink_to_fit` * `VecDeque::as_slices` * `VecDeque::as_mut_slices` * `VecDeque::swap_remove_front` - (renamed from `swap_front_remove`) * `VecDeque::swap_remove_back` - (renamed from `swap_back_remove`) * `Vec::resize` * `str::slice_mut_unchecked` * `FileTypeExt` * `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}` * `BinaryHeap::from` - `from_vec` deprecated in favor of this * `BinaryHeap::into_vec` - plus a `Into` impl * `BinaryHeap::into_sorted_vec` Deprecated APIs * `slice::ref_slice` * `slice::mut_ref_slice` * `iter::{range_inclusive, RangeInclusive}` * `std::dynamic_lib` Closes #27706 Closes #27725 cc #27726 (align not stabilized yet) Closes #27734 Closes #27737 Closes #27742 Closes #27743 Closes #27772 Closes #27774 Closes #27777 Closes #27781 cc #27788 (a few remaining methods though) Closes #27790 Closes #27793 Closes #27796 Closes #27810 cc #28147 (not all parts stabilized)

2015-09-11std: Stabilize/deprecate features for 1.4Alex Crichton-3/+4
The FCP is coming to a close and 1.4 is coming out soon, so this brings in the libs team decision for all library features this cycle. Stabilized APIs: * `<Box<str>>::into_string` * `Arc::downgrade` * `Arc::get_mut` * `Arc::make_mut` * `Arc::try_unwrap` * `Box::from_raw` * `Box::into_raw` * `CStr::to_str` * `CStr::to_string_lossy` * `CString::from_raw` * `CString::into_raw` * `IntoRawFd::into_raw_fd` * `IntoRawFd` * `IntoRawHandle::into_raw_handle` * `IntoRawHandle` * `IntoRawSocket::into_raw_socket` * `IntoRawSocket` * `Rc::downgrade` * `Rc::get_mut` * `Rc::make_mut` * `Rc::try_unwrap` * `Result::expect` * `String::into_boxed_slice` * `TcpSocket::read_timeout` * `TcpSocket::set_read_timeout` * `TcpSocket::set_write_timeout` * `TcpSocket::write_timeout` * `UdpSocket::read_timeout` * `UdpSocket::set_read_timeout` * `UdpSocket::set_write_timeout` * `UdpSocket::write_timeout` * `Vec::append` * `Vec::split_off` * `VecDeque::append` * `VecDeque::retain` * `VecDeque::split_off` * `rc::Weak::upgrade` * `rc::Weak` * `slice::Iter::as_slice` * `slice::IterMut::into_slice` * `str::CharIndices::as_str` * `str::Chars::as_str` * `str::split_at_mut` * `str::split_at` * `sync::Weak::upgrade` * `sync::Weak` * `thread::park_timeout` * `thread::sleep` Deprecated APIs * `BTreeMap::with_b` * `BTreeSet::with_b` * `Option::as_mut_slice` * `Option::as_slice` * `Result::as_mut_slice` * `Result::as_slice` * `f32::from_str_radix` * `f64::from_str_radix` Closes #27277 Closes #27718 Closes #27736 Closes #27764 Closes #27765 Closes #27766 Closes #27767 Closes #27768 Closes #27769 Closes #27771 Closes #27773 Closes #27775 Closes #27776 Closes #27785 Closes #27792 Closes #27795 Closes #27797

Fixes #27996.
2015-08-15core: Fill out issues for unstable featuresAlex Crichton-2/+4
2015-08-12Remove all unstable deprecated functionalityAlex Crichton-33/+1
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.
2015-07-29Rollup merge of #27326 - steveklabnik:doc_show_use, r=GankroSteve Klabnik-1/+2
In spirit with https://internals.rust-lang.org/t/should-we-keep-including-obvious-imports-in-code-examples/2217, show the feature flags we're using in examples. (also one instance of 'use')

2015-06-17std: Deprecate result::foldAlex Crichton-0/+3
This function has seen very little use and it seems better to explore this functionality through iterator adaptors instead of specialized functions.

2015-06-17core: Split apart the global `core` featureAlex Crichton-2/+3
This commit shards the broad `core` feature of the libcore library into finer grained features. This split groups together similar APIs and enables tracking each API separately, giving a better sense of where each feature is within the stabilization process. A few minor APIs were deprecated along the way: * Iterator::reverse_in_place * marker::NoCopy
2015-06-15libcore/Result - RFC#1119 Add an 'expect' method to ResultJohn Hodge-0/+20
2015-06-03Improve `try!` docs to make clearer it returns `Result`.Carol Nichols-1/+3
The API documentation is not explicit enough that because `try!` returns `Err` early for you, you can only use it in functions that return `Result`. The book mentions this, but if you come across `try!` outside of the book and look it up in the docs, this restriction on the return type of the function is not particularly clear.

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.

2015-04-06Alter libcore::result example to utilize closure paramCorey Farwell-1/+1
Since it doesn't utilize the parameter, it's not very idiomatic since it could just use the `Result::or` method. So this changes the example to utilize the parameter. As far as I can tell, all the numbers in this example are completely arbitrary.

2015-03-27rollup merge of #23752: alexcrichton/remove-should-failAlex Crichton-2/+2
This attribute has been deprecated in favor of #[should_panic]. This also updates rustdoc to no longer accept the `should_fail` directive and instead renames it to `should_panic`.
2015-03-26Update docs to fix various 404sGary M. Josack-1/+1
Found a few 404s that seemed like simple fixes: The Result docs use old_io Writer as an example. Fix the link to old_io Writer. There's probably an effort to update the example away from a deprecated api but this was a simple fix. rustc/plugin was pointing at the old guide and it was a broken link anyways (plugin vs plugins). Point at the book instead. The main page of the API docs referenced c_{str,vec}. Looks like these were deleted in 25d5a3a19423fee01787de87a56d185dd4e0a4e7. Point at ffi docs instead.

2015-03-23Add generic conversion traitsAaron Turon-1/+20
This commit: * Introduces `std::convert`, providing an implementation of RFC 529. * Deprecates the `AsPath`, `AsOsStr`, and `IntoBytes` traits, all in favor of the corresponding generic conversion traits. Consequently, various IO APIs now take `AsRef<Path>` rather than `AsPath`, and so on. Since the types provided by `std` implement both traits, this should cause relatively little breakage. * Deprecates many `from_foo` constructors in favor of `from`. * Changes `PathBuf::new` to take no argument (creating an empty buffer, as per convention). The previous behavior is now available as `PathBuf::from`. * De-stabilizes `IntoCow`. It's not clear whether we need this separate trait. Closes #22751 Closes #14433 [breaking-change]

This commit removes the reexports of `old_io` traits as well as `old_path` types and traits from the prelude. This functionality is now all deprecated and needs to be removed to make way for other functionality like `Seek` in the `std::io` module (currently reexported as `NewSeek` in the io prelude).

2015-02-27Rollup merge of #22817 - jmesmon:result-or-type, r=huonwManish Goregaokar-2/+2
Changes .or() so that it can return a Result with a different E type than the one it is called on. Essentially: fn or(self, res: Result<T, E>) -> Result<T, E> becomes fn or<F>(self, res: Result<T, F>) -> Result<T, F> This brings `or` in line with the existing `and` & `or_else` This is a [breaking-change] Due to some code needing additional type annotations.

2015-02-24Use arrays instead of vectors in testsVadim Petrochenkov-2/+2
2015-02-18make FromIterator use IntoIteratorAlexis-3/+4
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]
