Types

type FeatureGate

type FeatureGate map[string]bool

FeatureGate is map of key=value pairs that enables/disables various features.

func NewFeatures

func NewFeatures(rawFeatures string) (FeatureGate, error)

NewFeatures takes comma separated key=value pairs for features and returns a FeatureGate.

func (FeatureGate) Enabled

func (f FeatureGate) Enabled(feature string) bool

Enabled returns true if the feature gate value of a particular feature is true.

func (FeatureGate) Set

func (f FeatureGate) Set(s string) error

func (FeatureGate) String

func (f FeatureGate) String() string
