//! The separation between data structures and parsing follows the principle of separation of concerns.
//! Data structures (`rustc_attr_data_structures`) define what attributes look like after parsing.
//! Data structures (`rustc_hir::attrs`) define what attributes look like after parsing.
//! This crate (`rustc_attr_parsing`) handles how to convert raw tokens into those structures.
//! This split allows other parts of the compiler to use the data structures without needing
//! the parsing logic, making the codebase more modular and maintainable.
