Overview

Package internal contains functions/structs shared by xds balancers/resolvers.

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(l string) (LocalityID, error)

LocalityIDFromString converts a string representation of locality, of the form region:zone:sub-zone (as generated by the above String() method), into a LocalityID struct.

func (LocalityID) String

func (l LocalityID) String() string

String generates a string representation of LocalityID by adding ":" between the components of the LocalityID.
