타임라인​

Rust 1.32.0 (2019-01-17)​

  • Language
    • You can now use the ? operator in macro definitions. The ? operator allows you to specify zero or one repetitions similar to the * and + operators.
    • Module paths with no leading keyword like super, self, or crate, will now always resolve to the item (enum, struct, etc.) available in the module if present, before resolving to a external crate or an item the prelude. E.g. enum Color { Red, Green, Blue }
    • You can now match against PhantomData<T> types.
    • 그 외 4개 항목은 원문 참고
  • Compiler
    • The default allocator has changed from jemalloc to the default allocator on your system. The compiler itself on Linux & macOS will still use jemalloc, but programs compiled with it will use the system allocator.
    • Added the aarch64-pc-windows-msvc target.
  • Libraries
    • PathBuf now implements FromStr.
    • Box<[T]> now implements FromIterator<T>.
    • The dbg! macro has been stabilized. This macro enables you to easily debug expressions in your rust program. E.g. let a = 2; let b = dbg!(a * 2) + 1; // ^-- prints: [src/main.rs:4] a * 2 = 4 assert_eq!(b, 5);
    • 그 외 19개 항목은 원문 참고
  • Stabilized APIs
    • i8::to_be_bytes
    • i8::to_le_bytes
    • i8::to_ne_bytes
    • 그 외 69개 항목은 원문 참고
  • Cargo
    • You can now run cargo c as an alias for cargo check.
    • Usernames are now allowed in alt registry URLs.
  • Compatibility Notes
    • The argument types for AVX's _mm256_stream_si256, _mm256_stream_pd, _mm256_stream_ps have been changed from *const to *mut as the previous implementation was unsound.
