2017-09-29Auto merge of #44174 - jimmycuadra:try-from-infallible, r=sfacklerbors-0/+8
Add blanket TryFrom impl when From is implemented. Adds `impl<T, U> TryFrom<T> for U where U: From<T>`. Removes `impl<'a, T> TryFrom<&'a str> for T where T: FromStr` (originally added in #40281) due to overlapping impls caused by the new blanket impl. This removal is to be discussed further on the tracking issue for TryFrom. Refs #33417. /cc @sfackler, @scottmcm (thank you for the help!), and @aturon

2017-07-05rustc: Implement the #[global_allocator] attributeAlex Crichton-2/+2
This PR is an implementation of [RFC 1974] which specifies a new method of defining a global allocator for a program. This obsoletes the old `#![allocator]` attribute and also removes support for it. [RFC 1974]: https://github.com/rust-lang/rfcs/pull/197 The new `#[global_allocator]` attribute solves many issues encountered with the `#![allocator]` attribute such as composition and restrictions on the crate graph itself. The compiler now has much more control over the ABI of the allocator and how it's implemented, allowing much more freedom in terms of how this feature is implemented. cc #27389
2017-06-20Rollup merge of #42271 - tinaun:charfromstr, r=alexcrichtonCorey Farwell-0/+8
add `FromStr` Impl for `char` fixes #24939. is it possible to use pub(restricted) instead of using a stability attribute for the internal error representation? is it needed at all?

2016-04-11std: Stabilize APIs for the 1.9 releaseAlex Crichton-3/+8
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.

2015-08-15std: Add issues to all unstable featuresAlex Crichton-1/+2
2015-08-09Replace many uses of `mem::transmute` with more specific functionsTobias Bucher-2/+2
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`.
2015-07-28std: Stabilize a number of small APIsAlex Crichton-9/+93
The following APIs were all marked with a `#[stable]` tag: * process::Child::id * error::Error::is * error::Error::downcast * error::Error::downcast_ref * error::Error::downcast_mut * io::Error::get_ref * io::Error::get_mut * io::Error::into_inner * hash::Hash::hash_slice * hash::Hasher::write_{i,u}{8,16,32,64,size}
2015-06-17std: Hide some internal functions more aggressivelyAlex Crichton-1/+1
* Add `#[doc(hidden)]` * Rename away from `Error::description`
2015-06-17More test fixes and fallout of stability changesAlex Crichton-2/+2
2015-06-17core: Split apart the global `core` featureAlex Crichton-1/+1
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
2015-06-08Replace usage of String::from_str with String:fromSimon Sapin-1/+1
2015-05-01std: Don't use a wrapper for the float error typeAlex Crichton-1/+1
Ensures that the same error type is propagated throughout. Unnecessary leakage of the internals is prevented through the usage of stability attributes. Closes #24748
