Constants ¶

const XDSClientID = clientID("xdsClientID")

XDSClientID is the attributes key used to pass the address of the xdsClient object shared between the resolver and the balancer. The xdsClient object is created by the resolver and passed to the balancer.

Types ¶

type LocalityID ¶

type LocalityID struct {
	Region  string `json:"region,omitempty"`
	Zone    string `json:"zone,omitempty"`
	SubZone string `json:"subZone,omitempty"`
}

LocalityID is xds.Locality without XXX fields, so it can be used as map keys.

xds.Locality cannot be map keys because one of the XXX fields is a slice.

func LocalityIDFromString ¶

func LocalityIDFromString(s string) (ret LocalityID, _ error)

LocalityIDFromString converts a json representation of locality, into a LocalityID struct.

func (LocalityID) ToString ¶

func (l LocalityID) ToString() (string, error)

ToString generates a string representation of LocalityID by marshalling it into json. Not calling it String() so printf won't call it.
