Types

type KubeDiagFeatureGate

type KubeDiagFeatureGate interface {
	// Enabled returns true if the key is enabled.
	Enabled(featuregate.Feature) bool
	// KnownFeatures returns a slice of strings describing the known features.
	KnownFeatures() []string
	// SetFromMap stores flag gates for known features from a map[string]bool or returns an error.
	SetFromMap(map[string]bool) error
}

KubeDiagFeatureGate indicates whether a given feature is enabled or not and stores flag gates for known features.
