Rust
A language empowering everyone to build reliable and efficient software.
Rust overview
Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages.
Rust’s rich type system and ownership model guarantee memory-safety and thread-safety - enabling you to eliminate many classes of bugs at compile-time.
Rust has great documentation, a friendly compiler with useful error messages, and top-notch tooling - an integrated package manager and build tool, smart multi-editor support with auto-completion and type inspections, an auto-formatter, and more.
What’s new in version 1.64.0
Updated on Sep 23 2022
Language:
- Unions with mutable references or tuples of allowed types are now allowed
- It is now considered valid to deallocate memory pointed to by a shared reference &T if every byte in T is inside an UnsafeCell
- Unused tuple struct fields are now warned against in an allow-by-default lint, unused_tuple_struct_fields, similar to the existing warning for unused struct fields. This lint will become warn-by-default in the future.
Compiler:
- Add Nintendo Switch as tier 3 target
- Refer to Rust's platform support page for more information on Rust's tiered platform support.
- Only compile #[used] as llvm.compiler.used for ELF targets
- Add the --diagnostic-width compiler flag to define the terminal width.
- Add support for link-flavor rust-lld for iOS, tvOS and watchOS
Libraries:
- Remove restrictions on compare-exchange memory ordering.
- You can now write! or writeln! into an OsString: Implement fmt::Write for OsString
- Make RwLockReadGuard covariant
- Implement FusedIterator for std::net::[Into]Incoming
- impl AsRawFd for {Arc,Box}
- ptr::copy and ptr::swap are doing untyped copies
- Add cgroupv1 support to available_parallelism
- Mitigate many incorrect uses of mem::uninitialized
- And more
