Module metrics

Cache metrics system.

Provides a flexible metrics collection and reporting system for all cache algorithms. Each algorithm can track algorithm-specific metrics while implementing a common interface. Cache Metrics System

Provides a flexible metrics system for cache algorithms using BTreeMap-based metrics reporting. Each cache algorithm can track its own specific metrics while implementing a common CacheMetrics trait.

Why BTreeMap over HashMap?

BTreeMap is used instead of HashMap for several critical reasons:

• Deterministic ordering: Metrics always appear in consistent order
• Reproducible output: Essential for testing and benchmarking comparisons
• Stable serialization: JSON/CSV exports have predictable key ordering
• Better debugging: Consistent output makes logs more readable

The performance difference (O(log n) vs O(1)) is negligible with ~15 metric keys, but the deterministic behavior is invaluable for a simulation system.
