Fix ICE when combining #[eii] with #[core::contracts::ensures] Fixes rust-lang/rust#153745 Builtin attribute macros like #[eii] generate AST items programmatically without collected tokens. When another attribute macro was present on the same item, the compiler would panic in TokenStream::from_ast() trying to tokenize the generated items during subsequent attribute expansion. Generate fake token streams (via pretty-print and re-parse) for Item and ForeignItem nodes that lack collected tokens, following the existing pattern used for Crate and out-of-line modules.
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).
