Overview

Package snapversion generates xDS snapshot version strings for the agent cache.

A version string is "timestamp.counter.label" (e.g. "1704067200000.42.snapshot"): a Unix millisecond timestamp, an atomic counter increment, and a resource-type label. The timestamp+counter pair keeps versions unique and monotonically ordered so go-control-plane never applies an older snapshot after a newer one.

func Generate(label string, counter *atomic.Uint64) string

Generate creates a snapshot version string by combining a Unix millisecond timestamp, an atomic counter increment, and a label. The format is "timestamp.counter.label" (e.g., "1704067200000.42.listener"). This ensures version strings are unique and ordered.
