Revert "Also duplicate `#[expect]` attribute in `#[derive]`-ed code" Turns out rust-lang/rust#152289 doesn't work, not because cloning an attribute doesn't keep the same attribute id, but because `#[cfg]` and `#[cfg_attr]` [re-parse items from scratch](https://github.com/rust-lang/rust/blob/859951e3c7c9d0322c39bad49221937455bdffcd/compiler/rustc_builtin_macros/src/cfg_eval.rs#L100-L109) bypassing any cloning on AST and forcing the creation of new attribute IDs. 😕 Fixes rust-lang/rust#153036 Fixes rust-lang/rust#152401 Reopens rust-lang/rust#150553
This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
