# Recommended update for rust, rust1.75 Announcement ID: SUSE-RU-2024:0080-1 Rating: moderate References: * jsc#SLE-18626 Affected Products: * Development Tools Module 15-SP5 * openSUSE Leap 15.5 * SUSE Linux Enterprise Desktop 15 SP5 * SUSE Linux Enterprise High Performance Computing 15 SP5 * SUSE Linux Enterprise Real Time 15 SP5 * SUSE Linux Enterprise Server 15 SP5 * SUSE Linux Enterprise Server for SAP Applications 15 SP5 An update that contains one feature can now be installed. ## Description: This update for rust, rust1.75 fixes the following issues: This update ships rust 1.75. # Version 1.75.0 (2023-12-28) ## Language * Stabilize `async fn` and return-position `impl Trait` in traits. * Allow function pointer signatures containing `&mut T` in `const` contexts. * Match `usize`/`isize` exhaustively with half-open ranges. * Guarantee that `char` has the same size and alignment as `u32`. * Document that the null pointer has the 0 address. * Allow partially moved values in `match`. * Add notes about non-compliant FP behavior on 32bit x86 targets. * Stabilize ratified RISC-V target features. ## Compiler * Rework negative coherence to properly consider impls that only partly overlap. * Bump `COINDUCTIVE_OVERLAP_IN_COHERENCE` to deny, and warn in dependencies. * Consider alias bounds when computing liveness in NLL. * Add the V (vector) extension to the `riscv64-linux-android` target spec. * Automatically enable cross-crate inlining for small functions ## Libraries * Override `Waker::clone_from` to avoid cloning `Waker`s unnecessarily. * Implement `BufRead` for `VecDeque<u8>`. * Implement `FusedIterator` for `DecodeUtf16` when the inner iterator does. * Implement `Not, Bit{And,Or}{,Assign}` for IP addresses. * Implement `Default` for `ExitCode`. * Guarantee representation of None in NPO * Document when atomic loads are guaranteed read-only. * Broaden the consequences of recursive TLS initialization. * Windows: Support sub-millisecond sleep. * Fix generic bound of `str::SplitInclusive`'s `DoubleEndedIterator` impl * Fix exit status / wait status on non-Unix `cfg(unix)` platforms. ## Stabilized APIs * `Atomic*::from_ptr` * `FileTimes` * `FileTimesExt` * `File::set_modified` * `File::set_times` * `IpAddr::to_canonical` * `Ipv6Addr::to_canonical` * `Option::as_slice` * `Option::as_mut_slice` * `pointer::byte_add` * `pointer::byte_offset` * `pointer::byte_offset_from` * `pointer::byte_sub` * `pointer::wrapping_byte_add` * `pointer::wrapping_byte_offset` * `pointer::wrapping_byte_sub` These APIs are now stable in const contexts: * `Ipv6Addr::to_ipv4_mapped` * `MaybeUninit::assume_init_read` * `MaybeUninit::zeroed` * `mem::discriminant` * `mem::zeroed` ## Cargo * Add new packages to `[workspace.members * Allow version-less `Cargo.toml` manifests. * Make browser links out of HTML file paths. ## Rustdoc * Accept less invalid Rust in rustdoc. * Document lack of object safety on affected traits. * Hide `#[repr(transparent) * Show enum discriminant if it is a C-like variant. ## Compatibility Notes * Make misalignment a hard error in `const` contexts. * Fix detecting references to packed unsized fields. * Remove support for compiler plugins. ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
