- Update to version 1.41.1:
- Always check types of static items
- Always check lifetime bounds of `Copy` impls
- Fix miscompilation in callers of `Layout::repeat`
- Update to version 1.41.0:
+ Language
- You can now pass type parameters to foreign items when implementing
traits. E.g. You can now write `impl<T> From<Foo> for Vec<T> {}`.
- You can now arbitrarily nest receiver types in the `self` position. E.g. you can
now write `fn foo(self: Box<Box<Self>>) {}`. Previously only `Self`, `&Self`,
`&mut Self`, `Arc<Self>`, `Rc<Self>`, and `Box<Self>` were allowed.
- You can now use any valid identifier in a `format_args` macro.
Previously identifiers starting with an underscore were not allowed.
- Visibility modifiers (e.g. `pub`) are now syntactically allowed on trait items and
enum variants. These are still rejected semantically, but
can be seen and parsed by procedural macros and conditional compilation.
+ Compiler
- Rustc will now warn if you have unused loop `'label`s.
- Removed support for the `i686-unknown-dragonfly` target.
- Added tier 3 support\* for the `riscv64gc-unknown-linux-gnu` target.
- You can now pass an arguments file passing the `@path` syntax
to rustc. Note that the format differs somewhat from what is
found in other tooling; please see the documentation for
more information.
- You can now provide `--extern` flag without a path, indicating that it is
available from the search path or specified with an `-L` flag.
Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
+ Libraries
- The `core::panic` module is now stable. It was already stable
through `std`.
- `NonZero*` numerics now implement `From<NonZero*>` if it's a smaller integer
width. E.g. `NonZeroU16` now implements `From<NonZeroU8>`.
- `MaybeUninit<T>` now implements `fmt::Debug`.
+ Stabilized APIs
- `Result::map_or`
- `Result::map_or_else`
- `std::rc::Weak::weak_count`
- `std::rc::Weak::strong_count`
- `std::sync::Weak::weak_count`
- `std::sync::Weak::strong_count`
+ Cargo
- Cargo will now document all the private items for binary crates
by default.
- `cargo-install` will now reinstall the package if it detects that it is out
of date.
- Cargo.lock now uses a more git friendly format that should help to reduce
merge conflicts.
- You can now override specific dependencies's build settings. E.g.
`[profile.dev.package.image] opt-level = 2` sets the `image` crate's
optimisation level to `2` for debug builds. You can also use
`[profile.<profile>.build-override]` to override build scripts and
their dependencies.
+ Misc
- You can now specify `edition` in documentation code blocks to compile the block
for that edition. E.g. `edition2018` tells rustdoc that the code sample
should be compiled the 2018 edition of Rust.
- You can now provide custom themes to rustdoc with `--theme`, and check the
current theme with `--check-theme`.
- You can use `#[cfg(doc)]` to compile an item when building documentation.
+ Compatibility Notes
- As previously announced 1.41.0 will be the last tier 1 release for 32-bit
Apple targets. This means that the source code is still
available to build, but the targets are no longer being tested and release
binaries for those platforms will no longer be distributed by the Rust project.
Please refer to the linked blog post for more information.

- Add patch add-option-to-allow-warnings.patch to add a config option
which allows warnings and so enables v1.38 to bootstrap itself.
- Update to version 1.38.0
+ Language
- The `#[global_allocator]` attribute can now be used in submodules.
- The `#[deprecated]` attribute can now be used on macros.
+ Compiler
- Added pipelined compilation support to `rustc`. This will
improve compilation times in some cases.
+ Libraries
- `ascii::EscapeDefault` now implements `Clone` and `Display`.
- Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are now
available at the same path as the trait. (e.g. The `Clone` derive macro
is available at `std::clone::Clone`). This also makes all built-in macros
available in `std`/`core` root. e.g. `std::include_bytes!`.
- `str::Chars` now implements `Debug`.
- `slice::{concat, connect, join}` now accepts `&[T]` in addition to `&T`.
- `*const T` and `*mut T` now implement `marker::Unpin`.
- `Arc<[T]>` and `Rc<[T]>` now implement `FromIterator<T>`.
- Added euclidean remainder and division operations (`div_euclid`,

`overflowing`, and `wrapping` versions are available for all
integer primitives.
- `thread::AccessError` now implements `Clone`, `Copy`, `Eq`, `Error`, and
`PartialEq`.
- `iter::{StepBy, Peekable, Take}` now implement `DoubleEndedIterator`.

OBS-URL: https://build.opensuse.org/package/show/devel:languages:rust/rust?expand=0&rev=229
- Update to version 1.34.0
+ Language
- You can now use `#[deprecated = "reason"]` as a shorthand for
`#[deprecated(note = "reason")]`. This was previously allowed
by mistake but had no effect.
- You can now accept token streams in `#[attr()]`,`#[attr[]]`, and
`#[attr{}]` procedural macros.
- You can now write `extern crate self as foo;` to import your
crate's root into the extern prelude.
+ Compiler
- You can now target `riscv64imac-unknown-none-elf` and
`riscv64gc-unknown-none-elf`.
- You can now enable linker plugin LTO optimisations with
`-C linker-plugin-lto`. This allows rustc to compile your Rust
code into LLVM bitcode allowing LLVM to perform LTO optimisations
across C/C++ FFI boundaries.
- You can now target `powerpc64-unknown-freebsd`.
+ Libraries
- The trait bounds have been removed on some of `HashMap<K, V, S>`'s
and `HashSet<T, S>`'s basic methods. Most notably you no longer
require the `Hash` trait to create an iterator.
- The `Ord` trait bounds have been removed on some of
`BinaryHeap<T>`'s basic methods. Most notably you no longer require
the `Ord` trait to create an iterator.
- The methods `overflowing_neg` and `wrapping_neg` are now `const`
functions for all numeric types.
- Indexing a `str` is now generic over all types that
implement `SliceIndex<str>`.
- `str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and
`str::trim_{start, end}_matches` are now `#[must_use]` and will
produce a warning if their returning type is unused.
- The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and
`overflowing_pow` are now available for all numeric types. These are
equivalvent to methods such as `wrapping_add` for the `pow` operation.

- You can now use the `?` operator in your documentation
tests without manually adding `fn main() -> Result<(), _> {}`.
+ Compatibility Notes
- `Command::before_exec` is now deprecated in favor of the
unsafe method `Command::pre_exec`.
- Use of `ATOMIC_{BOOL, ISIZE, USIZE}_INIT` is now deprecated.
As you can now use `const` functions in `static` variables.
- Remove depreciated-trim_left_matches.patch.

- Use the system's LLVM in SLE15-SP1. That distribution has LLVM7,
and we need to use it there, instead of any other version.
- Prevent auto-provides from being created for things under

bundled LLVM and the Rust library files.
- Sync changes files between SLE and openSUSE, for ease of maintenance.

- Remove miri complete instead of excluding. This is experimental
and so should not be included.
- BuildRequires ccache in attempt to reduce compile times.
- Remove more extraneous directories from src that will never be
used.
- Extra patterns in rpmlintrc to catch more false positives:
+ Rust has no stable API, ignore SONAME warnings
+ Tool versions don't update in step with rust, ignore warnings
OBS-URL: https://build.opensuse.org/request/show/686253
OBS-URL: https://build.opensuse.org/package/show/devel:languages:rust/rust?expand=0&rev=202
- Update to version 1.33.0
+ Language
- You can now use the `cfg(target_vendor)` attribute. E.g.
`#[cfg(target_vendor="linux")] fn main() { println!("Hello Linux!"); }`
- Integer patterns such as in a match expression can now be exhaustive.
E.g. You can have match statement on a `u8` that covers `0..=255` and
you would no longer be required to have a `_ => unreachable!()` case.
- You can now have multiple patterns in `if let` and `while let`
expressions. You can do this with the same syntax as a `match`
expression. E.g.
```
enum Creature {
Crab(String),
Lobster(String),
Person(String),
}
fn main() {
let state = Creature::Crab("Ferris");
if let Creature::Crab(name) | Creature::Person(name) = state {
println!("This creature's name is: {}", name);
}
}
```
- You can now have irrefutable `if let` and `while let` patterns. Using
this feature will by default produce a warning as this behaviour can be
unintuitive. E.g. `if let _ = 5 {}`
- You can now use `let` bindings, assignments, expression statements,
and irrefutable pattern destructuring in const functions.
- You can now call unsafe const functions. E.g.
```
const unsafe fn foo() -> i32 { 5 }
const fn bar() -> i32 {
unsafe { foo() }
}
```
- You can now specify multiple attributes in a `cfg_attr` attribute.
E.g. `#[cfg_attr(all(), must_use, optimize)]`
- You can now specify a specific alignment with the `#[repr(packed)]`
attribute. E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a struct
with an alignment of 2 bytes and a size of 6 bytes.
- You can now import an item from a module as an `_`. This allows you to
import a trait's impls, and not have the name in the namespace. E.g.
```
use std::io::Read as _;
// Allowed as there is only one `Read` in the module.
pub trait Read {}
```
- extern` functions will now abort by default when panicking.
This was previously undefined behaviour.
+ Compiler
- You can now set a linker flavor for `rustc` with the `-Clinker-flavor`
command line argument.
- The mininum required LLVM version has been bumped to 6.0.
- Added support for the PowerPC64 architecture on FreeBSD.
- The `x86_64-fortanix-unknown-sgx` target support has been upgraded to
tier 2 support. Visit the [platform support][platform-support] page for
information on Rust's platform support.
- Added support for the `thumbv7neon-linux-androideabi` and
`thumbv7neon-unknown-linux-gnueabihf` targets.
- Added support for the `x86_64-unknown-uefi` target.
+ Libraries
- The methods `overflowing_{add, sub, mul, shl, shr}` are now `const`
functions for all numeric types.
- The methods `rotate_left`, `rotate_right`, and `wrapping_{add, sub, mul, shl, shr}`
are now `const` functions for all numeric types.
- The methods `is_positive` and `is_negative` are now `const` functions for
all signed numeric types.
- The `get` method for all `NonZero` types is now `const`.
- The methods `count_ones`, `count_zeros`, `leading_zeros`, `trailing_zeros`,
`swap_bytes`, `from_be`, `from_le`, `to_be`, `to_le` are now `const` for all
numeric types.

- Update to version 1.32.0
- Language
+ 2018 edition
- You can now use the `?` operator in macro definitions. The `?`
operator allows you to specify zero or one repetitions similar to the `*` and
`+` operators.
- Module paths with no leading keyword like `super`, `self`, or `crate`, will
now always resolve to the item (`enum`, `struct`, etc.) available in the
module if present, before resolving to a external crate or an item the prelude.
E.g.
enum Color { Red, Green, Blue }
use Color::*;
+ All editions
- You can now match against `PhantomData<T>` types.
- You can now match against literals in macros with the `literal`
specifier. This will match against a literal of any type.
E.g. `1`, `'A'`, `"Hello World"`
- Self can now be used as a constructor and pattern for unit and tuple structs. E.g.
struct Point(i32, i32);
impl Point {
pub fn new(x: i32, y: i32) -> Self {
Self(x, y)
}
pub fn is_origin(&self) -> bool {
match self {
Self(0, 0) => true,
_ => false,
}
}
}
- Self can also now be used in type definitions. E.g.
enum List<T>
where
Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
{
Nil,
Cons(T, Box<Self>) // likewise here
}
- You can now mark traits with `#[must_use]`. This provides a warning if
a `impl Trait` or `dyn Trait` is returned and unused in the program.
- Compiler
+ The default allocator has changed from jemalloc to the default allocator on
your system. The compiler itself on Linux & macOS will still use
jemalloc, but programs compiled with it will use the system allocator.
+ Added the `aarch64-pc-windows-msvc` target.
- Libraries
+ `PathBuf` now implements `FromStr`.
- `Box<[T]>` now implements `FromIterator<T>`.
- The `dbg!` macro has been stabilized. This macro enables you to
easily debug expressions in your rust program. E.g.
let a = 2;
let b = dbg!(a * 2) + 1;
// ^-- prints: [src/main.rs:4] a * 2 = 4
assert_eq!(b, 5);

- Update to version 1.31.0
+ Language
- This version marks the release of the 2018 edition of Rust.
- New lifetime elision rules now allow for eliding lifetimes in functions and
impl headers. E.g. `impl<'a> Reader for BufReader<'a> {}` can now be
`impl Reader for BufReader<'_> {}`. Lifetimes are still required to be defined
in structs.
- You can now define and use `const` functions. These are currently
a strict minimal subset of the const fn RFC. Refer to the
[language reference][const-reference] for what exactly is available.
- You can now use tool lints, which allow you to scope lints from external
tools using attributes. E.g. `#[allow(clippy::filter_map)]`.
- `#[no_mangle]` and `#[export_name]` attributes can now be located anywhere in
a crate, not just in exported functions.
- You can now use parentheses in pattern matches.
+ Compiler
- Updated musl to 1.1.20
+ Libraries
- You can now convert `num::NonZero*` types to their raw equivalvents using the
`From` trait. E.g. `u8` now implements `From<NonZeroU8>`.
- You can now convert a `&Option<T>` into `Option<&T>` and `&mut Option<T>`
into `Option<&mut T>` using the `From` trait.

- Patch: require patching of src/librustc_llvm/build.rs to ignore
a flag that llvm-config --cxxflags outputs which GCC doesn't
recognise.
- Default to building using the distro LLVM where the version is
>= 5.0, instead of the Rust bundled LLVM which requires
compilation. This should decrease build times. SLE LLVM is too old.
- Fixing various rpmlint warnings and errors:
+ ExclusiveArch instead of BuildArch for i686
+ Remove conflicts with same package name
+ Remove a few hidden files during prep, does not touch '.clang-format'
+ Remove old patch macro in comment
+ Fix lint warning about bash and zsh completition files
+ Fix various script shebang warnings (incorrect or missing)
+ Adjust rpmlintrc to mask some 'invalid' warnings
- Move Rust and its tools in to their own category under:
+ Development/Languages/Rust
- Jump from version 1.26.2 to 1.30.0 due to a build issue with using 1.26.x to
compile 1.27.x. This package release requires %{rust_bootstrap} to be set.
- Enable extra rust tools to be built (cargo, rls, rustfmt, analysis)
+ cargo is now packaged with the same version number as the rust release, this
may break any packages that relied on a cargo version number.
- Remove ccache and ninja from BuildRequires.
- Switch build configuration to use configure script, remove config.toml.
- Include all bootstraps in source rpm to make bootstrapping easier to manage
within OBS.
- Remove unused patch: update-config-guess.patch
Update to version 1.30.0 (2018-10-25)
+ Language
- Procedural macros are now available.- These kinds of macros allow for
more powerful code generation. There is a new chapter available
in the Rust Programming Language book that goes further in depth.
- You can now use keywords as identifiers using the raw identifiers
syntax (`r#`),- e.g. `let r#for = true;`
- Using anonymous parameters in traits is now deprecated with a warning and
will be a hard error in the 2018 edition.-
- You can now use `crate` in paths.- This allows you to refer to the
crate root in the path, e.g. `use crate::foo;` refers to `foo` in `src/lib.rs`.
- Using a external crate no longer requires being prefixed with `::`.-
Previously, using a external crate in a module without a use statement
required `let json = ::serde_json::from_str(foo);` but can now be written
as `let json = serde_json::from_str(foo);`.
- You can now apply the `#[used]` attribute to static items to prevent the
compiler from optimising them away, even if they appear to be unused,-
e.g. `#[used] static FOO: u32 = 1;`
- You can now import and reexport macros from other crates with the `use`
syntax.- Macros exported with `#[macro_export]` are now placed into
the root module of the crate. If your macro relies on calling other local
macros, it is recommended to export with the
`#[macro_export(local_inner_macros)]` attribute so users won't have to import
those macros.
- You can now catch visibility keywords (e.g. `pub`, `pub(crate)`) in macros
using the `vis` specifier.-
- Non-macro attributes now allow all forms of literals, not just
strings.- Previously, you would write `#[attr("true")]`, and you can now
write `#[attr(true)]`.
- You can now specify a function to handle a panic in the Rust runtime with the
`#[panic_handler]` attribute.-
+ Compiler
- Added the `riscv32imc-unknown-none-elf` target.-
- Added the `aarch64-unknown-netbsd` target-
+ Libraries
- `ManuallyDrop` now allows the inner type to be unsized.-
+ Stabilized APIs
- `Ipv4Addr::BROADCAST`
- `Ipv4Addr::LOCALHOST`
- `Ipv4Addr::UNSPECIFIED`
- `Ipv6Addr::LOCALHOST`
- `Ipv6Addr::UNSPECIFIED`
- `Iterator::find_map`
- The following methods are replacement methods for `trim_left`, `trim_right`,
`trim_left_matches`, and `trim_right_matches`, which will be deprecated
in 1.33.0:
+ `str::trim_end_matches`
+ `str::trim_end`
+ `str::trim_start_matches`
+ `str::trim_start`
+ Cargo
- `cargo run` doesn't require specifying a package in workspaces.][cargo/5877]
- `cargo doc` now supports `--message-format=json`.][cargo/5878] This is
equivalent to calling `rustdoc --error-format=json`.
- Cargo will now provide a progress bar for builds.][cargo/5995]
+ Misc
- `rustdoc` allows you to specify what edition to treat your code as with the
`--edition` option.-
- `rustdoc` now has the `--color` (specify whether to output color) and
`--error-format` (specify error format, e.g. `json`) options.-
- We now distribute a `rust-gdbgui` script that invokes `gdbgui` with Rust
debug symbols.-
- Attributes from Rust tools such as `rustfmt` or `clippy` are now
available,- e.g. `#[rustfmt::skip]` will skip formatting the next item.
- Update to version 1.29.2 (2018-10-11)
+ Workaround for an aliasing-related LLVM bug, which caused miscompilation.
+ The `rls-preview` component on the windows-gnu targets has been restored.
- Update to version 1.29.1 (2018-09-25)
+ Security Notes
- The standard library's `str::repeat` function contained an out of bounds write
caused by an integer overflow. This has been fixed by deterministically
panicking when an overflow happens.
- Update to version 1.29.0 (2018-09-13)
+ Compiler
- Bumped minimum LLVM version to 5.0.
- Added `powerpc64le-unknown-linux-musl` target.
- Added `aarch64-unknown-hermit` and `x86_64-unknown-hermit` targets.
+ Libraries
- `Once::call_once` no longer requires `Once` to be `'static`.
- `BuildHasherDefault` now implements `PartialEq` and `Eq`.
- `Box<CStr>`, `Box<OsStr>`, and `Box<Path>` now implement `Clone`.
- Implemented `PartialEq<&str>` for `OsString` and `PartialEq<OsString>`
for `&str`.
- `Cell<T>` now allows `T` to be unsized.
- `SocketAddr` is now stable on Redox.
+ Stabilized APIs
- `Arc::downcast`
- `Iterator::flatten`
- `Rc::downcast`
+ Cargo
- Cargo can silently fix some bad lockfiles.][cargo/5831] You can use
`--locked` to disable this behavior.
- `cargo-install` will now allow you to cross compile an install
using `--target`.][cargo/5614]
- Added the `cargo-fix` subcommand to automatically move project code from
2015 edition to 2018.][cargo/5723]
- `cargo doc` can now optionally document private types using the
`--document-private-items` flag.][cargo/5543]
+ Misc
- `rustdoc` now has the `--cap-lints` option which demotes all lints above
the specified level to that level. For example `--cap-lints warn`
will demote `deny` and `forbid` lints to `warn`.
- `rustc` and `rustdoc` will now have the exit code of `1` if compilation
fails and `101` if there is a panic.
- A preview of clippy has been made available through rustup.
You can install the preview with `rustup component add clippy-preview`.
+ Compatibility Notes
- `str::{slice_unchecked, slice_unchecked_mut}` are now deprecated.
Use `str::get_unchecked(begin..end)` instead.
- `std::env::home_dir` is now deprecated for its unintuitive behavior.
Consider using the `home_dir` function from
https://crates.io/crates/dirs instead.
- `rustc` will no longer silently ignore invalid data in target spec.
- `cfg` attributes and `--cfg` command line flags are now more
strictly validated.
- Update to version 1.28.0
+ Language
- The `#[repr(transparent)]` attribute is now stable.- This attribute
allows a Rust newtype wrapper (`struct NewType<T>(T);`) to be represented as
the inner type across Foreign Function Interface (FFI) boundaries.
- The keywords `pure`, `sizeof`, `alignof`, and `offsetof` have been unreserved
and can now be used as identifiers.-
- The `GlobalAlloc` trait and `#[global_allocator]` attribute are now
stable.- This will allow users to specify a global allocator for
their program.
- Unit test functions marked with the `#[test]` attribute can now return
`Result<(), E: Debug>` in addition to `()`.-
- The `lifetime` specifier for `macro_rules!` is now stable.- This
allows macros to easily target lifetimes.
+ Compiler
- The `s` and `z` optimisation levels are now stable.- These optimisations
prioritise making smaller binary sizes. `z` is the same as `s` with the
exception that it does not vectorise loops, which typically results in an even
smaller binary.
- The short error format is now stable.- Specified with
`--error-format=short` this option will provide a more compressed output of
rust error messages.
- Added a lint warning when you have duplicated `macro_export`s.-
- Reduced the number of allocations in the macro parser.- This can
improve compile times of macro heavy crates on average by 5%.
+ Libraries
- Implemented `Default` for `&mut str`.-
- Implemented `From<bool>` for all integer and unsigned number types.-
- Implemented `Extend` for `()`.-
- The `Debug` implementation of `time::Duration` should now be more easily
human readable.- Previously a `Duration` of one second would printed as
`Duration { secs: 1, nanos: 0 }` and will now be printed as `1s`.
- Implemented `From<&String>` for `Cow<str>`, `From<&Vec<T>>` for `Cow<[T]>`,
`From<Cow<CStr>>` for `CString`, `From<CString>, From<CStr>, From<&CString>`
for `Cow<CStr>`, `From<OsString>, From<OsStr>, From<&OsString>` for
`Cow<OsStr>`, `From<&PathBuf>` for `Cow<Path>`, and `From<Cow<Path>>`
for `PathBuf`.-
- Implemented `Shl` and `Shr` for `Wrapping<u128>`
and `Wrapping<i128>`.-
- `DirEntry::metadata` now uses `fstatat` instead of `lstat` when
possible.- This can provide up to a 40% speed increase.
- Improved error messages when using `format!`.-

+ Cargo
- Cargo will now no longer allow you to publish crates with build scripts that
modify the `src` directory.][cargo/5584] The `src` directory in a crate should be
considered to be immutable.
+ Misc
- The `suggestion_applicability` field in `rustc`'s json output is now
stable.- This will allow dev tools to check whether a code suggestion
would apply to them.
+ Compatibility Notes
- Rust will consider trait objects with duplicated constraints to be the same
type as without the duplicated constraint.- For example the below code will
now fail to compile.
```rust
trait Trait {}
impl Trait + Send {
fn test(&self) { println!("one"); } //~ ERROR duplicate definitions with name `test`
}
impl Trait + Send + Send {
fn test(&self) { println!("two"); }
}
- Update to version 1.27.2:
+ Compatibility Notes
- The borrow checker was fixed to avoid an additional potential unsoundness when using
match ergonomics
- Update to version 1.27.1:
+ Security Notes
- rustdoc would execute plugins in the /tmp/rustdoc/plugins directory
when running, which enabled executing code as some other user on a
given machine. This release fixes that vulnerability; you can read
more about this on the blog. The associated CVE is [CVE-2018-1000622].
Thank you to Red Hat for responsibily disclosing this vulnerability to us.
+ Compatibility Notes
- The borrow checker was fixed to avoid an additional potential unsoundness when using
match ergonomics
- Update to version 1.27.0:
+ Language
- Removed 'proc' from the reserved keywords list. This allows `proc` to
be used as an identifier.
- The dyn syntax is now available. This syntax is equivalent to the
bare `Trait` syntax, and should make it clearer when being used in tandem with
`impl Trait` because it is equivalent to the following syntax:
`&Trait == &dyn Trait`, `&mut Trait == &mut dyn Trait`, and
`Box<Trait> == Box<dyn Trait>`.
- Attributes on generic parameters such as types and lifetimes are
now stable. e.g.
`fn foo<#[lifetime_attr] 'a, #[type_attr] T: 'a>() {}`
- The `#[must_use]` attribute can now also be used on functions as well as
types. It provides a lint that by default warns users when the
value returned by a function has not been used.
+ Compiler
- Added the `armvte-unknown-linux-musleabi` target.
+ Libraries
- SIMD (Single Instruction Multiple Data) on x/x_ is now stable.
This includes arch::x & arch::x_ modules which contain
SIMD intrinsics, a new macro called `is_x_feature_detected!`, the
`#[target_feature(enable="")]` attribute, and adding `target_feature = ""` to
the `cfg` attribute.
- A lot of methods for `[u]`, `f`, and `f` previously only available in
std are now available in core.
- The generic `Rhs` type parameter on `ops::{Shl, ShlAssign, Shr}` now defaults
to `Self`.
- std::str::replace` now has the `#[must_use]` attribute to clarify
that the operation isn't done in place.
- Clone::clone`, `Iterator::collect`, and `ToOwned::to_owned` now have
the `#[must_use]` attribute] to warn about unused potentially
expensive allocations.

+ Cargo
- `cargo-metadata` now includes `authors`, `categories`, `keywords`,
`readme`, and `repository` fields.
- `cargo-metadata` now includes a package's `metadata` table.
- Added the `--target-dir` optional argument. This allows you to specify
a different directory than `target` for placing compilation artifacts.
- Cargo will be adding automatic target inference for binaries, benchmarks,
examples, and tests in the Rust 2018 edition. If your project specifies
specific targets, e.g. using `[[bin]]`, and have other binaries in locations
where cargo would infer a binary, Cargo will produce a warning. You can
disable this feature ahead of time by setting any of the following to false:
`autobins`, `autobenches`, `autoexamples`, `autotests`.
- Cargo will now cache compiler information. This can be disabled by
setting `CARGO_CACHE_RUSTC_INFO=0` in your environment.
+ Compatibility Notes
- Calling a `CharExt` or `StrExt` method directly on core will no longer
work. e.g. `::core::prelude::v1::StrExt::is_empty("")` will not
compile, `"".is_empty()` will still compile.
- `Debug` output on `atomic::{AtomicBool, AtomicIsize, AtomicPtr, AtomicUsize}`
will only print the inner type. E.g.
`print!("{:?}", AtomicBool::new(true))` will print `true`,
not `AtomicBool(true)`.
- The maximum number for `repr(align(N))` is now 2²⁹. Previously you
could enter higher numbers but they were not supported by LLVM. Up to 512MB
alignment should cover all use cases.
- The `.description()` method on the `std::error::Error` trait
has been soft-deprecated. It is no longer required to implement it.
+ Misc
- Added “The Rustc book” into the official documentation.
