trustformers-wasm 0.2.0

//! Automatic documentation generator from TypeScript definitions
//!
//! This module provides comprehensive documentation generation capabilities including:
//! - TypeScript definition parsing and analysis
//! - Multi-format documentation output (HTML, Markdown, JSON)
//! - API reference generation with examples
//! - Interactive playground documentation
//! - Theme support and customization
