2016-03-12std: Clean out deprecated APIsAlex Crichton-176/+1
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.
2016-03-11core: Make a new tracking issue for prelude traitsAlex Crichton-3/+3
The referenced issues here were both closed, so hook up a new issue which tracks specifically the prelude traits being unstable.
2016-03-11core: Mark Wrapping impls as stableAlex Crichton-5/+5
These are all insta-stable anyway, so just properly tag them.
2016-03-08doc: Fix a bunch of broken linksAlex Crichton-3/+3
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.
2016-03-01Rollup merge of #31965 - miqid:doc, r=steveklabnikSteve Klabnik-10/+10
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-10/+10
Redirects existing links for more details on primitive types in the `core` module to the ones that exist in the `std` module.
2016-02-29std: Stabilize APIs for the 1.8 releaseAlex Crichton-8/+8

2016-02-26Use .copy_from_slice() where applicableUlrik Sverdrup-2/+2
.copy_from_slice() does the same job of .clone_from_slice(), but the former is explicitly for Copy elements and calls `memcpy` directly, and thus is it efficient without optimization too.

2016-02-04Prevent the immediate panic uncovered by #31109 and add a test.Robin Kruppe-8/+28
The code there still triggers an ICE, but for different reasons (const eval unwraps the parse result).
2016-02-04Use the right target ratio in Algorithm M quickstart.Robin Kruppe-1/+1
Using f64's bit size probably wasn't actually *wrong*, but it would overshoot for no reason. This might have slowed down f32 parsing significantly.

2016-01-16std: Stabilize APIs for the 1.7 releaseAlex Crichton-82/+66
This commit stabilizes and deprecates the FCP (final comment period) APIs for the upcoming 1.7 beta release. The specific APIs which changed were: Stabilized * `Path::strip_prefix` (renamed from `relative_from`) * `path::StripPrefixError` (new error type returned from `strip_prefix`) * `Ipv4Addr::is_loopback` * `Ipv4Addr::is_private` * `Ipv4Addr::is_link_local` * `Ipv4Addr::is_multicast` * `Ipv4Addr::is_broadcast` * `Ipv4Addr::is_documentation` * `Ipv6Addr::is_unspecified` * `Ipv6Addr::is_loopback` * `Ipv6Addr::is_unique_local` * `Ipv6Addr::is_multicast` * `Vec::as_slice` * `Vec::as_mut_slice` * `String::as_str` * `String::as_mut_str` * `<[T]>::clone_from_slice` - the `usize` return value is removed * `<[T]>::sort_by_key` * `i32::checked_rem` (and other signed types) * `i32::checked_neg` (and other signed types) * `i32::checked_shl` (and other signed types) * `i32::checked_shr` (and other signed types) * `i32::saturating_mul` (and other signed types) * `i32::overflowing_add` (and other signed types) * `i32::overflowing_sub` (and other signed types) * `i32::overflowing_mul` (and other signed types) * `i32::overflowing_div` (and other signed types) * `i32::overflowing_rem` (and other signed types) * `i32::overflowing_neg` (and other signed types) * `i32::overflowing_shl` (and other signed types) * `i32::overflowing_shr` (and other signed types) * `u32::checked_rem` (and other unsigned types) * `u32::checked_neg` (and other unsigned types) * `u32::checked_shl` (and other unsigned types) * `u32::saturating_mul` (and other unsigned types) * `u32::overflowing_add` (and other unsigned types) * `u32::overflowing_sub` (and other unsigned types) * `u32::overflowing_mul` (and other unsigned types) * `u32::overflowing_div` (and other unsigned types) * `u32::overflowing_rem` (and other unsigned types) * `u32::overflowing_neg` (and other unsigned types) * `u32::overflowing_shl` (and other unsigned types) * `u32::overflowing_shr` (and other unsigned types) * `ffi::IntoStringError` * `CString::into_string` * `CString::into_bytes` * `CString::into_bytes_with_nul` * `From<CString> for Vec<u8>` * `From<CString> for Vec<u8>` * `IntoStringError::into_cstring` * `IntoStringError::utf8_error` * `Error for IntoStringError` Deprecated * `Path::relative_from` - renamed to `strip_prefix` * `Path::prefix` - use `components().next()` instead * `os::unix::fs` constants - moved to the `libc` crate * `fmt::{radix, Radix, RadixFmt}` - not used enough to stabilize * `IntoCow` - conflicts with `Into` and may come back later * `i32::{BITS, BYTES}` (and other integers) - not pulling their weight * `DebugTuple::formatter` - will be removed * `sync::Semaphore` - not used enough and confused with system semaphores Closes #23284 cc #27709 (still lots more methods though) Closes #27712 Closes #27722 Closes #27728 Closes #27735 Closes #27729 Closes #27755 Closes #27782 Closes #27798
2016-01-14Auto merge of #30466 - alexcrichton:move-wrapping-and-fill-out, r=aturonbors-14/+658
This commit migrates all of the methods on `num::wrapping::OverflowingOps` onto inherent methods of the integer types. This also fills out some missing gaps in the saturating and checked departments such as: * `saturating_mul` * `checked_{neg,rem,shl,shr}` This is done in preparation for stabilization, cc #27755
2016-01-13Auto merge of #30639 - rkruppe:dec2flt-fastpath-tables, r=alexcrichtonbors-9/+59
Add tables of small powers of ten used in the fast path. The tables are redundant: We could also use the big, more accurate table and round the value to the correct type (in fact we did just that before this commit). However, the rounding is extra work and slows down the fast path. Because only very small exponents enter the fast path, the table and thus the space overhead is negligible. Speed-wise, this is a clear win on a [benchmark] comparing the fast path to a naive, hand-optimized, inaccurate algorithm. Specifically, this change narrows the gap from a roughly 5x difference to a roughly 3.4x difference. [benchmark]: https://gist.github.com/Veedrac/dbb0c07994bc7882098e

2015-12-12dec2flt: Simplify imports and module surfaceRobin Kruppe-4/+4
The import has been unnecessarily complicated since ParseFloatError::Invalid is not longer used unqualified. The pfe_* functions do not need to be public any more since the only other use site, from_str_radix for floats, has been removed.

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-9/+42
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
