Module metadata 

Unity asset metadata processing module

This module provides comprehensive metadata extraction and analysis capabilities for Unity assets, organized following best practices for maintainability.

Architecture

The module is organized into several sub-modules:

• types - Core data structures for metadata representation
• extractor - Main metadata extraction functionality
• analyzer - Advanced dependency and relationship analysis

Examples

use unity_asset_binary::metadata::{MetadataExtractor, ExtractionConfig};
use unity_asset_binary::asset::{SerializedFile, SerializedFileHeader};

// Create extractor with custom configuration
let config = ExtractionConfig {
    include_dependencies: true,
    include_hierarchy: true,
    max_objects: Some(1000),
    include_performance: true,
    include_object_details: true,
};
let extractor = MetadataExtractor::with_config(config);

// Note: In real usage, you would load a SerializedFile from actual data
// For demonstration, we'll just show the extractor creation
println!("Extractor created with config");
println!("Metadata extracted successfully");
