Description: This update for rust, rust1.61 fixes the following issues: This updates ships rust1.61. Version 1.61.0 (2022-05-19) ========================== Language -------- - `const fn` signatures can now include generic trait bounds - `const fn` signatures can now use `impl Trait` in argument and return position - Function pointers can now be created, cast, and passed around in a `const fn` - Recursive calls can now set the value of a function's opaque `impl Trait` return type Compiler -------- - Linking modifier syntax in `#[link]` attributes and on the command line, as well as the `whole-archive` modifier specifically, are now supported - The `char` type is now described as UTF-32 in debuginfo - he [`#[target_feature]`][target_feature] attribute [can now be used with aarch64 features - X86 [`#[target_feature = "adx"]` is now stable Libraries --------- - `ManuallyDrop<T>` is now documented to have the same layout as `T` - `#[ignore = "���"]` messages are printed when running tests - Consistently show absent stdio handles on Windows as NULL handles - Make `std::io::stdio::lock()` return `'static` handles. Previously, the creation of locked handles to stdin/stdout/stderr would borrow the handles being locked, which prevented writing `let out = std::io::stdout().lock();` because `out` would outlive the return value of `stdout()`. Such code now works, eliminating a common pitfall that affected many Rust users. - `Vec::from_raw_parts` is now less restrictive about its inputs - `std::thread::available_parallelism` now takes cgroup quotas into account. Since `available_parallelism` is often used to create a thread pool for parallel computation, which may be CPU-bound for performance, `available_parallelism` will return a value consistent with the ability to use that many threads continuously, if possible. For instance, in a container with 8 virtual CPUs but quotas only allowing for 50% usage, `available_parallelism` will return 4. Stabilized APIs --------------- - `Pin::static_mut` - `Pin::static_ref` - `Vec::retain_mut` - `VecDeque::retain_mut` - `Write` for `Cursor<[u8; N]>` - `std::os::unix::net::SocketAddr::from_pathname` - `std::process::ExitCode` and `std::process::Termination`. The stabilization of these two APIs now makes it possible for programs to return errors from `main` with custom exit codes. - `std::thread::JoinHandle::is_finished`] These APIs are now usable in const contexts: - `<*const T>::offset` and `<*mut T>::offset` - `<*const T>::wrapping_offset` and `<*mut T>::wrapping_offset` - `<*const T>::add` and `<*mut T>::add` - `<*const T>::sub` and `<*mut T>::sub` - `<*const T>::wrapping_add` and `<*mut T>::wrapping_add` - `<*const T>::wrapping_sub` and `<*mut T>::wrapping_sub` - `<[T]>::as_mut_ptr` - `<[T]>::as_ptr_range` - `<[T]>::as_mut_ptr_range` Cargo ----- No feature changes, but see compatibility notes. Compatibility Notes ------------------- - Previously native static libraries were linked as `whole-archive` in some cases, but now rustc tries not to use `whole-archive` unless explicitly requested. This change may result in linking errors in some cases. To fix such errors, native libraries linked from the command line, build scripts, or [`#[link]` attributes][link-attr] need to - (more common) either be reordered to respect dependencies between them (if `a` depends on `b` then `a` should go first and `b` second) - (less common) or be updated to use the [`+whole-archive`] modifier. - Catching a second unwind from FFI code while cleaning up from a Rust panic now causes the process to abort - Proc macros no longer see `ident` matchers wrapped in groups - The number of `#` in `r#` raw string literals is now required to be less than 256 - When checking that a dyn type satisfies a trait bound, supertrait bounds are now enforced - `cargo vendor` now only accepts one value for each `--sync` flag - `cfg` predicates in `all()` and `any()` are always evaluated to detect errors, instead of short-circuiting. The compatibility considerations here arise in nightly-only code that used the short-circuiting behavior of `all` to write something like `cfg(all(feature = "nightly", syntax-requiring-nightly))`, which will now fail to compile. Instead, use either `cfg_attr(feature = "nightly", ...)` or nested uses of `cfg`. - bootstrap: static-libstdcpp is now enabled by default, and can now be disabled when llvm-tools is enabled Patch Instructions: To install this SUSE Recommended Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
