1//! Convert rustdoc JSON output to clean, LLM-friendly markdown documentation.
2//!
3//! This library provides functionality to parse rustdoc's JSON output and convert it
4//! to well-formatted markdown files suitable for LLM consumption and text-based viewing.
5//!
6//! # Example
7//!
8//! ```no_run
9//! use rustdoc_json_to_markdown::{convert_json_file, ConversionOptions};
10//! use std::path::Path;
11//!
12//! let options = ConversionOptions {
13//!     input_path: Path::new("target/doc/my_crate.json"),
14//!     output_dir: Path::new("docs"),
15//!     include_private: false,
16//! };
17//!
18//! convert_json_file(&options).expect("Conversion failed");
19//! ```
