+//! `kebab-parse-code::rust` — tree-sitter Rust AST extractor (P10-1A-2).
+//!
+//! Implements [`kebab_core::Extractor`] for [`MediaType::Code("rust")`].
+//! Walks the tree-sitter parse tree and emits one [`Block::Code`] per
+//! top-level AST semantic unit (free fn, type, trait, macro, each impl
+//! method, recursively per module), each carrying [`SourceSpan::Code`]
+//! with the unit's self-reference symbol path (design §3.4). Glue
+//! declarations (`use` / `const` / `static` / bodyless `mod` / top-level
+//! attributes / macro invocations) collapse into one grouped
+//! `<top-level>` (or `<module>`) unit.
+//!
+//! Doc comments and attributes immediately preceding an item are folded
+//! into that item's line range (design §9.1 "선언 + doc comment").
+//!
+//! Scope is intentionally narrow: AST unit extraction + symbol paths +
+//! line ranges for Rust. The `CanonicalDocument` scaffold mirrors
+//! `kebab-parse-pdf`. Per design §3.4 / §9.1 / §9 versioning.
