Crate pcm_engine 

Product Catalog Engine (PCM) Framework

The Product Catalog Engine is the heart of the BSS, providing business agility through efficient management of pricing, eligibility, and bundling rules.

This framework abstracts the complexity of:

• Pricing rules and calculations
• Product eligibility validation
• Bundling and product relationships
• Catalog versioning and lifecycle management

Built with Rust’s safety guarantees to prevent costly billing errors.
