Struct Registry 

pub struct Registry { /* private fields */ }

A thread-safe registry for storing metrics by name.

Stores one Arc-wrapped instance per unique metric name for each enabled metric type. Repeated lookups for the same name return the same Arc (pointer equality holds). Only metric types enabled via Cargo features are compiled in; attempting to call a method for a disabled type will result in a compile-time error.

Cache-line aligned to prevent false sharing in concurrent environments.
