Struct UsageTracker

coderd/workspacestats/tracker.go:30–42

UsageTracker tracks and de-bounces updates to workspace usage activity. It keeps an internal map of workspace IDs that have been used and periodically flushes this to its configured Store.

// It keeps an internal map of workspace IDs that have been used and
// periodically flushes this to its configured Store.
type UsageTracker struct {
	log         slog.Logger      // you know, for logs
