- Update to 1.23.0
- Language changes:
+ Arbitrary `auto` traits are now permitted in trait objects.[45772]
+ rustc now uses subtyping on the left hand side of binary operations.[45435]
Which should fix some confusing errors in some operations.
- Compiler changes:
+ Enabled `TrapUnreachable` in LLVM which should mitigate the impact of
undefined behaviour.[45920]
+ rustc now suggests renaming import if names clash.[45660]
+ Display errors/warnings correctly when there are zero-width or
wide characters.[45711]
+ rustc now avoids unnecessary copies of arguments that are
simple bindings[45380] This should improve memory usage on average by 5-10%.
+ Updated musl used to build musl rustc to 1.1.17[45393]
- Library changes:
+ Allow a trailing comma in `assert_eq/ne` macro[45887]
+ Implement Hash for raw pointers to unsized types[45483]
+ impl `From<*mut T>` for `AtomicPtr<T>`[45610]
+ impl `From<usize/isize>` for `AtomicUsize/AtomicIsize`.[45610]
+ Removed the `T: Sync` requirement for `RwLock<T>: Send`[45267]
+ Removed `T: Sized` requirement for `{<*const T>, <*mut T>}::as_ref`
an `<*mut T>::as_mut`[44932]
+ Optimized `Thread::{park, unpark}` implementation[45524]
+ Improved `SliceExt::binary_search` performance.[45333]
+ impl `FromIterator<()>` for `()`[45379]
+ Copied `AsciiExt` trait methods to primitive types.[44042] Use of `AsciiExt`
is now deprecated.
- Misc changes:
+ Releases now ship with the Cargo book documentation.[45692]
+ rustdoc now prints rendering warnings on every run.[45324]
+ Release tarballs now come with rustfmt[45903]
- Compatibility Notes:
+ Changes have been made to type equality to make it more correct,
in rare cases this could break some code.[45853] [Tracking issue for
further information[45852]
+ `char::escape_debug` now uses Unicode 10 over 9.[45571]
+ Upgraded Android SDK to 27, and NDK to r15c.[45580] This drops support for
Android 9, the minimum supported version is Android 14.
+ Bumped the minimum LLVM to 3.9[45326]
