Struct MetricsRegistry

pub struct MetricsRegistry { /* private fields */ }

Central registry for metrics in the KhoraEngine

This registry provides a high-level API for metrics management and serves as the main entry point for the metrics system. It handles metric registration, updates, and queries while providing type safety and convenient helper methods.
