Detailed Description

Basic metric structure for interface compatibility.

A generic metric container that can hold different value types (double, int64_t, or string) along with metadata tags and type information. Supports conversion to compact representation for efficient storage.

Thread Safety:

This struct is NOT thread-safe. External synchronization is required when accessed from multiple threads.
