1//! # DDEX Builder - Deterministic DDEX XML Generation
2//! 
3//! A high-performance, memory-safe DDEX XML builder that generates deterministic,
4//! byte-perfect XML using DB-C14N/1.0 canonicalization. Built in Rust with
5//! comprehensive security features and bindings for JavaScript, Python, and WebAssembly.
6//!
7//! ## Key Features
8//!
9//! - **🔒 Security First**: XXE protection, input validation, rate limiting, and comprehensive security measures
10//! - **⚡ High Performance**: Sub-millisecond generation for typical releases, memory-optimized streaming
11//! - **🎯 Deterministic Output**: Guaranteed byte-perfect reproducibility using DB-C14N/1.0
12//! - **🔄 Round-trip Fidelity**: Perfect compatibility with ddex-parser for Parse → Build → Parse workflows
13//! - **🛠️ Partner Presets**: Pre-configured settings for Spotify, YouTube, Apple Music, and other platforms
14//! - **🌐 Multi-platform**: Native Rust, Node.js, Python, and WebAssembly bindings
15//! - **📊 Version Support**: Full support for ERN 3.8.2, 4.2, 4.3 with automatic conversion
16//!
17//! ## Quick Start
18//!
19//! ```rust
20//! use ddex_builder::{Builder, DdexVersion};
21//! use ddex_builder::builder::{BuildRequest, OutputFormat};
22//!
23//! // Create a builder with Spotify preset
24//! let mut builder = Builder::new();
25//! builder.preset("spotify_audio_43")?;
26//!
27//! // Build DDEX XML
28//! let request = BuildRequest {
29//!     source_xml: r#"<SoundRecording>...</SoundRecording>"#.to_string(),
30//!     output_format: OutputFormat::Xml,
31//!     preset: Some("spotify_audio_43".to_string()),
32//!     validate_schema: true,
33//! };
34//!
35//! let result = builder.build_internal(&request)?;
36//! println!("Generated DDEX XML: {}", result.xml);
37//! # Ok::<(), ddex_builder::BuildError>(())
38//! ```
39//!
40//! ## Security Features
41//!
42//! DDEX Builder includes comprehensive security measures:
43//!
44//! ```rust
45//! use ddex_builder::{InputValidator, SecurityConfig, ApiSecurityManager};
46//!
47//! // Configure security settings
48//! let security_config = SecurityConfig {
49//!     max_xml_size: 10_000_000,        // 10MB limit
50//!     max_json_depth: 32,              // Prevent deep nesting attacks
51//!     rate_limiting_enabled: true,
52//!     max_requests_per_minute: 100,
53//!     validate_urls: true,
54//!     block_private_ips: true,
55//!     ..Default::default()
56//! };
57//!
58//! // Validate inputs
59//! let validator = InputValidator::new(security_config.clone());
60//! validator.validate_xml_content(&xml_input)?;
61//!
62//! // API security management
63//! let mut api_security = ApiSecurityManager::new(security_config);
64//! api_security.validate_request("build", "client_id", xml_input.len())?;
65//! # Ok::<(), ddex_builder::BuildError>(())
66//! ```

404/// The main DDEX Builder for creating deterministic XML output.
405///
406/// `Builder` is the primary interface for generating DDEX-compliant XML with
407/// guaranteed deterministic output. It supports partner presets, version conversion,
408/// and comprehensive security features.
409///
410/// ## Features
411///
412/// - **Deterministic Output**: Uses DB-C14N/1.0 for byte-perfect reproducibility
413/// - **Partner Presets**: Pre-configured settings for major music platforms
414/// - **Version Management**: Support for ERN 3.8.2, 4.2, and 4.3 with conversion
415/// - **Security**: Built-in validation, rate limiting, and XXE protection
416/// - **Performance**: Memory-optimized with streaming support for large files
417///
418/// ## Usage Patterns
419///
420/// ### Basic Usage
421///
422/// ```rust
423/// use ddex_builder::Builder;
424///
425/// let builder = Builder::new();
426/// let available_presets = builder.available_presets();
427/// println!("Available presets: {:?}", available_presets);
428/// ```
429///
430/// ### With Partner Preset
431///
432/// ```rust
433/// use ddex_builder::Builder;
434///
435/// let mut builder = Builder::new();
436/// builder.preset("spotify_audio_43")?;
437/// 
438/// // Builder is now configured for Spotify Audio releases (ERN 4.3)
439/// assert!(builder.is_preset_locked() == false); // Unlocked for further customization
440/// # Ok::<(), ddex_builder::BuildError>(())
441/// ```
442///
443/// ### Locked Preset Configuration
444///
445/// ```rust
446/// use ddex_builder::Builder;
447///
448/// let mut builder = Builder::new();
449/// builder.apply_preset("spotify_audio_43", true)?; // Lock the preset
450/// 
451/// assert!(builder.is_preset_locked());
452/// # Ok::<(), ddex_builder::BuildError>(())
453/// ```
454///
455/// ### Version Conversion
456///
457/// ```rust
458/// use ddex_builder::{Builder, DdexVersion};
459/// use ddex_builder::versions::ConversionOptions;
460///
461/// let builder = Builder::new();
462/// 
463/// // Check version compatibility
464/// let compatible = builder.is_version_compatible(
465///     DdexVersion::Ern382, 
466///     DdexVersion::Ern43
467/// );
468/// 
469/// if compatible {
470///     let options = Some(ConversionOptions::default());
471///     let result = builder.convert_version(
472///         &xml_content,
473///         DdexVersion::Ern382,
474///         DdexVersion::Ern43,
475///         options
476///     )?;
477///     println!("Converted XML: {}", result.converted_xml);
478/// }
479/// # let xml_content = "<test></test>";
480/// # Ok::<(), ddex_builder::BuildError>(())
481/// ```
482///
483/// ## Thread Safety
484///
485/// `Builder` is `Send + Sync` and can be safely shared between threads.
486/// Each thread should create its own instance for best performance.
487///
488/// ## Memory Usage
489///
490/// The builder uses memory-optimized data structures and streaming
491/// where possible. Typical memory usage:
492/// - Small releases (<100KB): ~5MB
493/// - Large releases (>1MB): ~20-50MB with streaming
