- Update to version 1.50:
* This fixes build on armv7 - boo#1181643
+ Language
- You can now use const values for x in [x; N] array expressions.
This has been technically possible since 1.38.0, as it was
unintentionally stabilized.
- Assignments to ManuallyDrop<T> union fields are now considered safe.
+ Compiler
- Added tier 3* support for the armv5te-unknown-linux-uclibceabi
target.
- Added tier 3 support for the aarch64-apple-ios-macabi target.
- The x86_64-unknown-freebsd is now built with the full toolset.
- Dropped support for all cloudabi targets.
* Refer to Rust's platform support page for more information on
Rust's tiered platform support.
+ Libraries
- proc_macro::Punct now implements PartialEq<char>.
- ops::{Index, IndexMut} are now implemented for fixed sized
arrays of any length.
- On Unix platforms, the std::fs::File type now has a "niche" of -1.
This value cannot be a valid file descriptor, and now means Option<File>
takes up the same amount of space as File.
+ Stabilized APIs
bool::then
btree_map::Entry::or_insert_with_key
f32::clamp
f64::clamp
hash_map::Entry::or_insert_with_key
Ord::clamp
RefCell::take
slice::fill
UnsafeCell::get_mut
- The following previously stable methods are now const.
IpAddr::is_ipv4
IpAddr::is_ipv6
IpAddr::is_unspecified
IpAddr::is_loopback
IpAddr::is_multicast
Ipv4Addr::octets
Ipv4Addr::is_loopback
Ipv4Addr::is_private
Ipv4Addr::is_link_local
Ipv4Addr::is_multicast
Ipv4Addr::is_broadcast
Ipv4Addr::is_documentation
Ipv4Addr::to_ipv6_compatible
Ipv4Addr::to_ipv6_mapped
Ipv6Addr::segments
Ipv6Addr::is_unspecified
Ipv6Addr::is_loopback
Ipv6Addr::is_multicast
Ipv6Addr::to_ipv4
Layout::size
Layout::align
Layout::from_size_align
pow for all integer types.
checked_pow for all integer types.
saturating_pow for all integer types.
wrapping_pow for all integer types.
next_power_of_two for all unsigned integer types.
checked_next_power_of_two for all unsigned integer types.
+ Cargo
- Added the [build.rustc-workspace-wrapper] option. This option
sets a wrapper to execute instead of rustc, for workspace members only.
- cargo:rerun-if-changed will now, if provided a directory,
scan the entire contents of that directory for changes.
- Added the --workspace flag to the cargo update command.
+ Misc
- The search results tab and the help button are focusable
with keyboard in rustdoc.
- Running tests will now print the total time taken to execute.
+ Compatibility Notes
- The compare_and_swap method on atomics has been deprecated.
It's recommended to use the compare_exchange and
compare_exchange_weak methods instead.
- Changes in how TokenStreams are checked have fixed some cases
where you could write unhygenic macro_rules! macros.
- #![test] as an inner attribute is now considered unstable
like other inner macro attributes, and reports an error by
default through the soft_unstable lint.
- Overriding a forbid lint at the same level that it was set
is now a hard error.
- You can no longer intercept panic! calls by supplying your own
macro. It's recommended to use the #[panic_handler] attribute
to provide your own implementation.
- Semi-colons after item statements (e.g. struct Foo {};)
now produce a warning.
- Add download_helper.sh to ease download of bootstrap packages

# Automatic updating via _service Edit the spec file, and update the variables related with the version (in format X.YY.Z): - *version_current*: for the new version of Rust - *version_previous*: for the previous version of Rust - *version_bootstrap*: for the version used to compile Rust, it recommended to use the same version that *version_previous* - *rustfmt_version*: for the version of rustfmt cli, check the tarball to find the correct version - *clippy_version*: for the version of clippy, check the tarball to find the correct version After that, we can execute the service file: osc service disabledrun If `osc` complains about a missing service component, double check that the components are installed. For example, for Tumbleweed: zypper in obs-service-download_files obs-service-refresh_patches Finally, update the changelog based on the releases notes: https://github.com/rust-lang/rust/blob/master/RELEASES.md # Updating to a new version from upstream (Original link: https://en.opensuse.org/Rust) Branch the rust package in the devel:languages:rust project. You'll need to download precompiled binaries for the compiler used for bootstrapping, and the actual source code for the compiler. In the "Other Installation Methods" page listed below, note that it shows links to .tar.gz packages and their .tar.gz.asc GPG signatures, but .tar.xz versions are also available. *Binaries for bootstrapping* - Go to the "Other Installation Methods" page from rust-lang.org and scroll down to the "Standalone installers" section. Download the following: - rust-<version>-aarch64-unknown-linux-gnu.tar.xz - rust-<version>-armv7-unknown-linux-gnueabihf.tar.xz - rust-<version>-i686-unknown-linux-gnu.tar.xz - rust-<version>-powerpc64le-unknown-linux-gnu.tar.xz - rust-<version>-powerpc64-unknown-linux-gnu.tar.xz - rust-<version>-s390x-unknown-linux-gnu.tar.xz - rust-<version>-x86_64-unknown-linux-gnu.tar.xz *Compiler source code* - From the same page, but now in the "Source code" section, download this: rustc-<version>-src.tar.xz Update those files in the source RPM. Check that all the patches still apply. Update the version number in rust.spec. Add the release notes to rust.changes.
