composer.rs

//!
//! Extracts package metadata and dependencies from PHP Composer manifests
//! (composer.json) and lockfiles (composer.lock).
//!
//! # Supported Formats
//! - composer.json (manifest)
//! - composer.lock (lockfile)
//!
//! # Key Features
//! - Dependency extraction from require and require-dev
//! - PSR-4 autoload and repository metadata capture
//! - Locked dependency versions with dist/source hashes
//!
//! # Implementation Notes
//! - Uses serde_json for parsing
//! - Graceful error handling with warn!()
//! - Package URL (purl) generation via packageurl
//!
