Announcing Rust 1.82.0 | Rust Blog

  • Rust 1.82.0 is released, featuring various improvements and new features.
  • Cargo info subcommand: Displays information about a package in the registry, including version, license, and documentation.
  • Apple target promotions: macOS on 64-bit ARM is now a Tier 1 target, and Mac Catalyst targets are now Tier 2.
  • Precise capturing use<..> syntax: Allows controlling which generic lifetime parameters are captured in certain impl Trait bounds.
  • Native syntax for creating raw pointers: Introduces &raw const and &raw mut operators for creating raw pointers without references.
  • Other notable changes: Include safe items with unsafe extern, omitting empty types in pattern matching, standardized NaN semantics, and stabilized APIs.

Please let me know if this meets your requirements or if I should make any adjustments.

Detailed Key Points (5 bullet points with brief explanations):

  1. Cargo info subcommand: A new subcommand for Cargo that displays detailed information about a package in the registry, including its version, license, and documentation links.
  2. Tier 1 support for macOS on 64-bit ARM: The Rust target aarch64-apple-darwin is now a Tier 1 target, ensuring it passes full tests before merging changes to the Rust repository.
  3. Precise capturing with use<..> syntax: This feature allows developers to control which generic lifetime parameters are captured in certain impl Trait bounds, improving the handling of opaque types and their lifetimes.
  4. Native raw pointer creation syntax: Introduces &raw const and &raw mut operators to create raw pointers directly without first creating a reference, enhancing safety and clarity in unsafe code.
  5. Standardized NaN semantics and const support: Rust now standardizes the behavior of NaN (Not a Number) values in floating-point operations, enabling their use in const fn contexts while ensuring portability across different hardware architectures.
