타임라인​

Rust 1.92.0 (2025-12-11)​

  • Language
    • Document MaybeUninit representation and validity — source
    • Allow &raw [mut | const] for union field in safe code — source
    • Prefer item bounds of associated types over where-bounds for auto-traits and Sized — source
    • 그 외 6개 항목은 원문 참고
  • Compiler
    • Make mips64el-unknown-linux-muslabi64 link dynamically — source
    • Remove current code for embedding command-line args in PDB Command-line information is typically not needed by debugging tools, and the removed code was causing problems for incremental builds even on targets that don't use PDB debuginfo. — source
  • Libraries
    • Specialize Iterator::eq{_by} for TrustedLen iterators — source
    • Simplify Extend for tuples — source
    • Added details to Debug for EncodeWide . — source
    • 그 외 1개 항목은 원문 참고
  • Stabilized APIs
    • NonZero<u{N}>::div_ceil — source
    • Location::file_as_c_str — source
    • RwLockWriteGuard::downgrade — source
    • 그 외 14개 항목은 원문 참고
  • Cargo
    • Added a new chapter to the Cargo book, "Optimizing Build Performance". — source
  • Rustdoc
    • If a trait item appears in rustdoc search, hide the corresponding impl items . Previously a search for "last" would show both Iterator::last as well as impl methods like std::vec::IntoIter::last. Now these impl methods will be hidden, freeing up space for inherent methods like BTreeSet::last. — source
    • Relax rules for identifiers in search . Previously you could only search for identifiers that were valid in rust code, now searches only need to be valid as part of an identifier. For example, you can now perform a search that starts with a digit. — source
