<summary>Recommended update for rust, rust1.65</summary>
<description>This update for rust, rust1.65 fixes the following issues:
This update provides rust1.65 (jsc#SLE-18626)
Version 1.65.0 (2022-11-03)
==========================
Language
--------
- Error on `as` casts of enums with `#[non_exhaustive]` variants
- Stabilize `let else`
- Stabilize generic associated types (GATs)
- Add lints `let_underscore_drop`, `let_underscore_lock`, and `let_underscore_must_use` from Clippy
- Stabilize `break`ing from arbitrary labeled blocks ("label-break-value")
- Uninitialized integers, floats, and raw pointers are now considered immediate UB
sage of `MaybeUninit` is the correct way to work with uninitialized memory.
- Stabilize raw-dylib for Windows x86_64, aarch64, and thumbv7a
- Do not allow `Drop` impl on foreign ADTs
Compiler
--------
- Stabilize -Csplit-debuginfo on Linux
- Use niche-filling optimization even when multiple variants have data
- Associated type projections are now verified to be well-formed prior to resolving the underlying type
- Stringify non-shorthand visibility correctly
- Normalize struct field types when unsizing
- Update to LLVM 15
- Fix aarch64 call abi to correctly zeroext when needed
- debuginfo: Generalize C++-like encoding for enums
- Add `special_module_name` lint
- Add support for generating unique profraw files by default when using `-C instrument-coverage`
- Allow dynamic linking for iOS/tvOS targets
Libraries
---------
- Don't generate `PartialEq::ne` in derive(PartialEq)
- Windows RNG: Use `BCRYPT_RNG_ALG_HANDLE` by default
- Forbid mixing `System` with direct system allocator calls
- Document no support for writing to non-blocking stdio/stderr
- `std::layout::Layout` size must not overflow `isize::MAX` when rounded up to `align`
This also changes the safety conditions on `Layout::from_size_align_unchecked`.
Stabilized APIs
---------------
- `std::backtrace::Backtrace`
- `Bound::as_ref`
- `std::io::read_to_string`
- `<*const T>::cast_mut`
- `<*mut T>::cast_const`
Thse APIs are now stable in const contexts:
- `<*const T>::offset_from`
- `<*mut T>::offset_from`
Cargo
-----
- Apply GitHub fast path even for partial hashes
- Do not add home bin path to PATH if it's already there
- Take priority into account within the pending queue
This slightly optimizes job scheduling by Cargo, with typically small improvements on larger crate graph builds.
Compatibility Notes
-------------------
- `std::layout::Layout` size must not overflow `isize::MAX` when rounded up to `align`
This also changes the safety conditions on `Layout::from_size_align_unchecked`.
- `PollFn` now only implements `Unpin` if the closure is `Unpin`
This is a possible breaking change if users were relying on the blanket unpin implementation.
See discussion on the PR for details of why this change was made.
- Drop ExactSizeIterator impl from std::char::EscapeAscii
This is a backwards-incompatible change to the standard library's surface
area, but is unlikely to affect real world usage.
- Do not consider a single repeated lifetime eligible for elision in the return type
This behavior was unintentionally changed in 1.64.0, and this release reverts that change by making this an error again.
- Reenable disabled early syntax gates as future-incompatibility lints
- Update the minimum external LLVM to 13
- Don't duplicate file descriptors into stdio fds
- Sunset RLS
- Deny usage of `#![cfg_attr(..., crate_type = ...)]` to set the crate type
This strengthens the forward compatibility lint deprecated_cfg_attr_crate_type_name to deny.
- `llvm-has-rust-patches` allows setting the build system to treat the LLVM as having Rust-specific patches
This option may need to be set for distributions that are building Rust with a patched LLVM via `llvm-config`, not the built-in LLVM.
Changes in rust:
- Update to version 1.65.0 - for details see the rust1.65 package
- Enable armv6 again - bsc#1196328
This update also ships "cargo-auditable", a tool to embed crate information into ELF binaries.
