타임라인​

Rust 1.26.0 (2018-05-10)​

  • Language
    • Closures now implement Copy and/or Clone if all captured variables implement either or both traits.
    • The inclusive range syntax e.g. for x in 0..=10 is now stable.
    • The '_ lifetime is now stable. The underscore lifetime can be used anywhere a lifetime can be elided.
    • 그 외 6개 항목은 원문 참고
  • Compiler
    • LLD is now used as the default linker for wasm32-unknown-unknown.
    • Fixed exponential projection complexity on nested types. This can provide up to a ~12% reduction in compile times for certain crates.
    • Added the --remap-path-prefix option to rustc. Allowing you to remap path prefixes outputted by the compiler.
    • 그 외 1개 항목은 원문 참고
  • Libraries
    • Implemented From<u16> for usize & From<{u8, i16}> for isize.
    • Added hexadecimal formatting for integers with fmt::Debug e.g. assert!(format!("{:02x?}", b"Foo\0") == "[46, 6f, 6f, 00]")
    • Implemented Default, Hash for cmp::Reverse.
    • 그 외 5개 항목은 원문 참고
  • Stabilized APIs
    • *const T::add
    • *const T::copy_to_nonoverlapping
    • *const T::copy_to
    • 그 외 37개 항목은 원문 참고
  • Cargo
    • Cargo will now output path to custom commands when -v is passed with --list
    • The Cargo binary version is now the same as the Rust version
  • Compatibility Notes
    • aliasing a Fn trait as dyn no longer works. E.g. the following syntax is now invalid. use std::ops::Fn as dyn; fn g(_: Box<dyn(std::fmt::Debug)>) {}
    • The result of dereferences are no longer promoted to 'static. e.g. fn main() { const PAIR: &(i32, i32) = &(0, 1); let _reversed_pair: &'static _ = &(PAIR.1, PAIR.0); // Doesn't work }
    • Deprecate AsciiExt trait in favor of inherent methods.
    • 그 외 3개 항목은 원문 참고
