The unstable book, libstd, libcore, and liballoc all needed some adjustment.
2017-03-20Auto merge of #40281 - jimmycuadra:try-from-from-str, r=aturonbors-2/+2
Rename TryFrom's associated type and implement str::parse using TryFrom. Per discussion on the tracking issue, naming `TryFrom`'s associated type `Error` is generally more consistent with similar traits in the Rust ecosystem, and what people seem to assume it should be called. It also helps disambiguate from `Result::Err`, the most common "Err". See https://github.com/rust-lang/rust/issues/33417#issuecomment-269108968. `TryFrom<&str>` and `FromStr` are equivalent, so have the latter provide the former to ensure that. Using `TryFrom` in the implementation of `str::parse` means types that implement either trait can use it. When we're ready to stabilize `TryFrom`, we should update `FromStr` to suggest implementing `TryFrom<&str>` instead for new code. See https://github.com/rust-lang/rust/issues/33417#issuecomment-277175994 and https://github.com/rust-lang/rust/issues/33417#issuecomment-277253827. Refs #33417.

2017-03-13Remove function invokation parens from documentation links.Corey Farwell-10/+10
This was never established as a convention we should follow in the 'More API Documentation Conventions' RFC: https://github.com/rust-lang/rfcs/blob/master/text/1574-more-api-documentation-conventions.md
2017-01-29Fix a few impl stability attributesOliver Middleton-3/+3

2016-11-30Rename 'librustc_unicode' crate to 'libstd_unicode'.Corey Farwell-1/+1
Fixes #26554.
2016-11-23Use "radices" instead of "radicum"Sam Estep-1/+1
2016-09-28[breaking-change] std: change `encode_utf{8,16}()` to take a buffer and ↵tormol-119/+51
return a slice They panic if the buffer is too small.
2016-09-18Add missing Eq implementationsGuillaume Gomez-1/+1
2016-08-29Implement TryFrom<u32> for charSimon Sapin-6/+29
For symmetry with From<char> for u32.
2016-08-29Implement From<char> for u32, and From<u8> for charSimon Sapin-0/+34
These fit with other From implementations between integer types. This helps the coding style of avoiding the 'as' operator that sometimes silently truncates, and signals that these specific conversions are lossless and infaillible.

2016-08-18Add a FusedIterator trait.Steven Allen-0/+18
This trait can be used to avoid the overhead of a fuse wrapper when an iterator is already well-behaved. Conforming to: RFC 1581 Closes: #35602
2016-07-28Rename `char::escape` to `char::escape_debug` and add tracking issueTobias Bucher-12/+12
2016-07-26Restore `char::escape_default` and add `char::escape` insteadTobias Bucher-1/+37
2016-07-23Escape fewer Unicode codepoints in `Debug` impl of `str`Tobias Bucher-2/+3
Use the same procedure as Python to determine whether a character is printable, described in [PEP 3138]. In particular, this means that the following character classes are escaped: - Cc (Other, Control) - Cf (Other, Format) - Cs (Other, Surrogate), even though they can't appear in Rust strings - Co (Other, Private Use) - Cn (Other, Not Assigned) - Zl (Separator, Line) - Zp (Separator, Paragraph) - Zs (Separator, Space), except for the ASCII space `' '` (`0x20`) This allows for user-friendly inspection of strings that are not English (e.g. compare `"\u{e9}\u{e8}\u{ea}"` to `"éèê"`). Fixes #34318. [PEP 3138]: https://www.python.org/dev/peps/pep-3138/

Simply a micro-optimization to reduce code size and to open up inlining opportunities.

and reuse it in `size_hint`.
2016-05-26Implement `count` for `EscapeDefault` and `EscapeUnicode`Andrea Canciani-6/+7
Trivial implementation, as both are `ExactSizeIterator`s. Part of #24214.
2016-05-26`EscapeUnicode` and `EscapeDefault` are `ExactSizeIterator`sAndrea Canciani-0/+6
In #28662, `size_hint` was made exact for `EscapeUnicode` and `EscapeDefault`, but neither was marked as `ExactSizeIterator`.

2016-04-20Implement `last` for `EscapeUnicode`Andrea Canciani-0/+12
Part of #24214.
2016-04-19Auto merge of #31253 - ranma42:improve-unicode-iter-offset, r=brsonbors-20/+32
Improve computation of offset in `EscapeUnicode` Unify the computation of `offset` and use `leading_zeros` instead of manually scanning the bits. This PR removes some duplicated code and makes it a little simpler . The computation of `offset` is also faster, but it is unlikely to have an impact on actual code. (split from #31049)
2016-03-22std: Change `encode_utf{8,16}` to return iteratorsAlex Crichton-70/+119
Currently these have non-traditional APIs which take a buffer and report how much was filled in, but they're not necessarily ergonomic to use. Returning an iterator which *also* exposes an underlying slice shouldn't result in any performance loss as it's just a lazy version of the same implementation, and it's also much more ergonomic! cc #27784

A few categories: * Links into compiler docs were just all removed as we're not generating compiler docs. * Move up one more level to forcibly go to std docs to fix inlined documentation across the facade crates.

2016-01-28Improve computation of `EscapeUnicode` offset fieldAndrea Canciani-5/+7
Instead of iteratively scanning the bits, use `leading_zeros`.
2016-01-28Unify computation of length in `EscapeUnicode`Andrea Canciani-20/+22
The `offset` value was computed both in `next` and in `size_hint`; computing it in a single place ensures consistency and makes it easier to apply improvements. The value is now computed as soon as the iterator is constructed. This means that the time to compute it is spent immediately and cannot be avoided, but it also guarantees that it is only spent once.

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-3/+9
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
