Language
|

--------
|
||||
- [Fixed displaying duplicate errors on some trait bounds.][45772]
|
||||
- [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
|

--------
|

- [Enabled `TrapUnreachable` in LLVM which should prevent some cases of

- [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 uses subtyping on the left hand side of binary operations.][45435]
|
||||
Which should fix some confusing errors in some operations.
|
||||
- [Bumped the minimum LLVM to 3.9][45326]
|
||||
- [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]
|
||||
- [Refactored type memory layouts and ABIs.][45225] This will reduce
|
||||
memory size for some types. Eg. `io::Result<()>` is now 16 bytes
|
||||
where it was previously 24.

Libraries
|
||||
---------
|
||||
- [impl `From<T>` for `Mutex<T>` and `RwLock<T>`][46082]
|
||||
- [Allow a trailling comma in `assert_eq/ne` macro][45887]
|
||||
- [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<{number_size}>` for `Atomic{number_size}`][45610] eg. `From<u8>`
|
||||
for `AtomicU8`.
|
||||
- [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>::as_ref`
|
||||
and `<*const T>::as_mut`][44932]
|
||||
- [Removed `T: Sized` requirement for `{<*const T>, <*mut T>}::as_ref`
|
||||
and `<*mut T>::as_mut`][44932]
|
||||
- [Optimized `Thread::{park, unpark}` implementation][45524]
|
||||
- [Improved `SliceExt::binary_search` performance.][45333]
|
||||
- [Optimized `Read::read_to_end`.][46050] This increase file read speed and for
|
||||
small files reduce the number of syscalls.
|
||||
- [impl `FromIterator<()>` for `()`][45379]
|
||||
- [Copied `AsciiExt` trait methods to primitive types.][44042] Use of `AsciiExt`
|
||||
is now deprecated.

Compatibility Notes
|
||||
-------------------
|
||||
- [`fmt::Arguments` can no longer be shared across threads.][45198]
|
||||
- [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]
|
||||
- [Changed how closures are stored, as a result of this change you can no longer
|
||||
have a situation where a closure directly calls itself.][45879]
|
||||
- [`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.
|
||||
- [Refactored type memory layouts and ABIs.][45225] This reduce code generated
|
||||
for a lot of types.
|
||||
|
||||
- [Bumped the minimum LLVM to 3.9][45326]
