3//! Multi-language code structure analysis library using tree-sitter.
4//!
5//! This crate provides core analysis functionality for extracting code structure
6//! from multiple programming languages. It is designed to be used as a library
7//! by MCP servers and other tools.
8//!
9//! # Features
10//!
11//! - **Language support**: Rust, Go, Java, Python, TypeScript, TSX, Fortran, JavaScript, C/C++, C# (feature-gated)
12//! - **Schema generation**: Optional JSON schema support via the `schemars` feature
13//! - **Async-friendly**: Uses tokio for concurrent analysis
14//! - **Cancellation support**: Built-in cancellation token support
15//!
16//! # Examples
17//!
18//! ```no_run
19//! use aptu_coder_core::analyze::analyze_directory;
20//! use std::path::Path;
21//!
22//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
23//! let output = analyze_directory(Path::new("src"), None)?;
24//! println!("Files: {:?}", output.files.len());
25//! # Ok(())
26//! # }
27//! ```

92/// Execute a custom tree-sitter query against source code.
93///
94/// # Arguments
95///
96/// * `language` - Language name (e.g., "rust", "python"). Must be an enabled language feature.
97/// * `source` - Source code to query.
98/// * `query` - A tree-sitter query string (S-expression syntax).
99///
100/// # Returns
101///
102/// A vector of [`QueryCapture`] results, or a [`ParserError`] if the query is malformed
103/// or the language is not supported.
104///
105/// # Security note
106///
107/// This function accepts user-controlled `query` strings. Pathological queries against
108/// large `source` inputs may cause CPU exhaustion. Callers in untrusted environments
109/// should bound the length of both `source` and `query` before calling this function.
110/// `Query::new()` returns `Err` on malformed queries rather than panicking.
