1//! deagle-parse — tree-sitter based code parser.
2//!
3//! Extracts code entities (functions, structs, traits, impls, imports)
4//! from source files using tree-sitter grammars.
5//!
6//! ## Feature Flags
7//!
8//! - `pattern` — structural pattern matching via [ast-grep-core](https://crates.io/crates/ast-grep-core)
