Recommended update for rust, rust1.67
SUSE-SLE-Module-Development-Tools-15-SP4-2023-290
This update for rust, rust1.67 fixes the following issues: Rust is shipped in version 1.67.0. Changes in rust1.67: Version 1.67.0 (2023-01-26) ========================== Language -------- - Make `Sized` predicates coinductive, allowing cycles. - #[must_use]` annotations on `async fn` also affect the `Future::Output`. - Elaborate supertrait obligations when deducing closure signatures. - Invalid literals are no longer an error under `cfg(FALSE)`. - Unreserve braced enum variants in value namespace. Compiler -------- - Enable varargs support for calling conventions other than `C` or `cdecl`. - Add new MIR constant propagation based on dataflow analysis. - Optimize field ordering by grouping m\*2^n-sized fields with equivalently aligned ones. - Stabilize native library modifier `verbatim`. Added and removed targets: - Remove tier 3 `linuxkernel` targets Refer to Rust's platform support page for more information on Rust's tiered platform support. Libraries --------- - Merge `crossbeam-channel` into `std::sync::mpsc`. - Fix inconsistent rounding of 0.5 when formatted to 0 decimal places. - Derive `Eq` and `Hash` for `ControlFlow`. - Don't build `compiler_builtins` with `-C panic=abort`. Stabilized APIs --------------- - {integer}::checked_ilog - {integer}::checked_ilog2 - {integer}::checked_ilog10 - {integer}::ilog - {integer}::ilog2 - {integer}::ilog10 - NonZeroU*::ilog2 - NonZeroU*::ilog10 - NonZero*::BITS These APIs are now stable in const contexts: - char::from_u32 - char::from_digit - char::to_digit - core::char::from_u32 - core::char::from_digit Compatibility Notes ------------------- - The layout of `repr(Rust)` types now groups m\*2^n-sized fields with equivalently aligned ones. This is intended to be an optimization, but it is also known to increase type sizes in a few cases for the placement of enum tags. As a reminder, the layout of `repr(Rust)` types is an implementation detail, subject to change. - 0.5 now rounds to 0 when formatted to 0 decimal places. This makes it consistent with the rest of floating point formatting that rounds ties toward even digits. - Chains of `&&` and `||` will now drop temporaries from their sub-expressions in evaluation order, left-to-right. Previously, it was "twisted" such that the _first_ expression dropped its temporaries _last_, after all of the other expressions dropped in order. - Underscore suffixes on string literals are now a hard error. This has been a future-compatibility warning since 1.20.0. - Stop passing `-export-dynamic` to `wasm-ld`. - main` is now mangled as `__main_void` on `wasm32-wasi`. - Cargo now emits an error if there are multiple registries in the configuration with the same index URL.
