<patchinfo incident="26302"> <packager>firstyear</packager> <rating>moderate</rating> <issue tracker="jsc" id="SLE-18626"></issue> <category>recommended</category> <summary>Recommended update for rust</summary> <description>This update for rust fixes the following issues: Rust was updated to ship in version 1.64.0 in rust1.64. Version 1.64.0 (2022-09-22) =========================== Language -------- - Unions with mutable references or tuples of allowed types are now allowed - It is now considered valid to deallocate memory pointed to by a shared reference `&T` [if every byte in `T` is inside an `UnsafeCell`] - Unused tuple struct fields are now warned against in an allow-by-default lint, [`unused_tuple_struct_fields`] Compiler -------- - Add Nintendo Switch as tier 3 target - Refer to Rust's platform support page for more information on Rust's tiered platform support. - Only compile `#[used]` as llvm.compiler.used for ELF targets - Add the `--diagnostic-width` compiler flag to define the terminal width. - Add support for link-flavor `rust-lld` for iOS, tvOS and watchOS Libraries --------- - Remove restrictions on compare-exchange memory ordering. - You can now `write!` or `writeln!` into an `OsString`: [Implement `fmt::Write` for `OsString`] - Make RwLockReadGuard covariant - Implement `FusedIterator` for `std::net::[Into]Incoming` - `impl<T: AsRawFd> AsRawFd for {Arc,Box}<T>` - `ptr::copy` and `ptr::swap` are doing untyped copies - Add cgroupv1 support to `available_parallelism` - Mitigate many incorrect uses of `mem::uninitialized` Stabilized APIs --------------- - future::IntoFuture - future::poll_fn - task::ready! - num::NonZero*::checked_mul - num::NonZero*::checked_pow - num::NonZero*::saturating_mul - num::NonZero*::saturating_pow - num::NonZeroI*::abs - num::NonZeroI*::checked_abs - num::NonZeroI*::overflowing_abs - num::NonZeroI*::saturating_abs - num::NonZeroI*::unsigned_abs - num::NonZeroI*::wrapping_abs - num::NonZeroU*::checked_add - num::NonZeroU*::checked_next_power_of_two - num::NonZeroU*::saturating_add - os::unix::process::CommandExt::process_group - os::windows::fs::FileTypeExt::is_symlink_dir - os::windows::fs::FileTypeExt::is_symlink_file These types were previously stable in std::ffi, but are now also available in core and alloc: - core::ffi::CStr - core::ffi::FromBytesWithNulError - alloc::ffi::CString - alloc::ffi::FromVecWithNulError - alloc::ffi::IntoStringError - alloc::ffi::NulError These types were previously stable in std::os::raw, but are now also available in core::ffi and std::ffi: - ffi::c_char - ffi::c_double - ffi::c_float - ffi::c_int - ffi::c_long - ffi::c_longlong - ffi::c_schar - ffi::c_short - ffi::c_uchar - ffi::c_uint - ffi::c_ulong - ffi::c_ulonglong - ffi::c_ushort These APIs are now usable in const contexts: - slice::from_raw_parts Cargo ----- - Packages can now inherit settings from the workspace so that the settings can be centralized in one place. - Cargo commands can now accept multiple `--target` flags to build for multiple targets at once - The --jobs argument can now take a negative number to count backwards from the max CPUs. - cargo add will now update Cargo.lock. - Added the --crate-type flag to `cargo rustc` to override the crate type. - Significantly improved the performance fetching git dependencies from GitHub when using a hash in the `rev` field. Misc ---- - The rust-analyzer rustup component is now available on the stable channel. Compatibility Notes ------------------- - The minimum required versions for all -linux-nu` targets are now at least kernel 3.2 and glibc 2.17, for targets that previously supported older versions. - Network primitives are now implemented with the ideal Rust layout, not the C system layout - Add assertion that `transmute_copy`'s `U` is not larger than `T` - A soundness bug in `BTreeMap` was fixed - The Drop behavior of C-like enums cast to ints has changed - Relate late-bound closure lifetimes to parent fn in NLL - Errors at const-eval time are now in future incompatibility reports - On the `thumbv6m-none-eabi` target, some incorrect `asm!` statements were erroneously accepted if they used the high registers (r8 to r14) as an input/output operand. This is no longer accepted. - `impl Trait` was accidentally accepted as the associated type value of return-position `impl Trait`, without fulfilling all the trait bounds of that associated type, as long as the hidden type satisfies said bounds. This has been fixed. </description> </patchinfo>
