Accepting request 694642 from home:luke_nukem:branches:devel:languages:rust - Update to version 1.34.0 + Language - You can now use `#[deprecated = "reason"]` as a shorthand for `#[deprecated(note = "reason")]`. This was previously allowed by mistake but had no effect. - You can now accept token streams in `#[attr()]`,`#[attr[]]`, and `#[attr{}]` procedural macros. - You can now write `extern crate self as foo;` to import your crate's root into the extern prelude. + Compiler - You can now target `riscv64imac-unknown-none-elf` and `riscv64gc-unknown-none-elf`. - You can now enable linker plugin LTO optimisations with `-C linker-plugin-lto`. This allows rustc to compile your Rust code into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI boundaries. - You can now target `powerpc64-unknown-freebsd`. + Libraries - The trait bounds have been removed on some of `HashMap<K, V, S>`'s and `HashSet<T, S>`'s basic methods. Most notably you no longer require the `Hash` trait to create an iterator. - The `Ord` trait bounds have been removed on some of `BinaryHeap<T>`'s basic methods. Most notably you no longer require the `Ord` trait to create an iterator. - The methods `overflowing_neg` and `wrapping_neg` are now `const` functions for all numeric types. - Indexing a `str` is now generic over all types that implement `SliceIndex<str>`. - `str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and `str::trim_{start, end}_matches` are now `#[must_use]` and will produce a warning if their returning type is unused. - The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and `overflowing_pow` are now available for all numeric types. These are equivalvent to methods such as `wrapping_add` for the `pow` operation. + Stabilized APIs - std & core + Any::type_id + Error::type_id + atomic::AtomicI16 + atomic::AtomicI32 + atomic::AtomicI64 + atomic::AtomicI8 + atomic::AtomicU16 + atomic::AtomicU32 + atomic::AtomicU64 + atomic::AtomicU8 + convert::Infallible + convert::TryFrom + convert::TryInto + iter::from_fn + iter::successors + num::NonZeroI128 + num::NonZeroI16 + num::NonZeroI32 + num::NonZeroI64 + num::NonZeroI8 + num::NonZeroIsize + slice::sort_by_cached_key + str::escape_debug + str::escape_default + str::escape_unicode + str::split_ascii_whitespace - std + Instant::checked_add + Instant::checked_sub + SystemTime::checked_add + SystemTime::checked_sub + Cargo - You can now use alternative registries to crates.io. + Misc - You can now use the `?` operator in your documentation tests without manually adding `fn main() -> Result<(), _> {}`. + Compatibility Notes - `Command::before_exec` is now deprecated in favor of the unsafe method `Command::pre_exec`. - Use of `ATOMIC_{BOOL, ISIZE, USIZE}_INIT` is now deprecated. As you can now use `const` functions in `static` variables. - Remove depreciated-trim_left_matches.patch. - Rustfmt version bumped to 1.0.3 + Change description not provided. - rls version now in sync with rustc. - Misc fixes to rust.spec OBS-URL: https://build.opensuse.org/request/show/694642 OBS-URL: https://build.opensuse.org/package/show/devel:languages:rust/rust?expand=0&rev=213 2019-04-16 10:32:05 +00:00			`version https://git-lfs.github.com/spec/v1`
