type Collection Uses

❖
type Collection []Instance

func (Collection) IsSupersetOf Uses

IsSupersetOf returns true if the input labels are a subset set of any set of labels in a collection

type Instance Uses

❖
type Instance map[string]string

Instance is a non empty map of arbitrary strings. Each version of a service can be differentiated by a unique set of labels associated with the version. These labels are assigned to all instances of a particular service version.

func (Instance) SubsetOf Uses

❖
func (i Instance) SubsetOf(that Instance) bool
