type Feature

type Feature string

type FeatureGate

type FeatureGate interface {
	// Enabled returns true if the key is enabled.
	Enabled(key Feature) bool
	// KnownFeatures returns a slice of strings describing the FeatureGate's known features.
	KnownFeatures() []string
	// DeepCopy returns a deep copy of the FeatureGate object, such that gates can be
	// set on the copy without mutating the original. This is useful for validating
	// config against potential feature gate changes before committing those changes.
	DeepCopy() MutableFeatureGate

FeatureGate indicates whether a given feature is enabled or not

type FeatureSpec

type FeatureSpec struct {
	// Default is the default enablement state for the feature
	Default bool
	// LockToDefault indicates that the feature is locked to its default and cannot be changed
	LockToDefault bool
	// PreRelease indicates the maturity level of the feature
	PreRelease prerelease

type MutableFeatureGate

type MutableFeatureGate interface {

	// AddFlag adds a flag for setting global feature gates to the specified FlagSet.
	AddFlag(fs *pflag.FlagSet)
	// Set parses and stores flag gates for known features
	// from a string like feature1=true,feature2=false,...
	Set(value string) error
	// SetFromMap stores flag gates for known features from a map[string]bool or returns an error
	SetFromMap(m map[string]bool) error
	// Add adds features to the featureGate.
	Add(features map[Feature]FeatureSpec) error

MutableFeatureGate parses and stores flag gates for known features from a string like feature1=true,feature2=false,...
