Types

type XDSConfig

type XDSConfig struct {
	serviceconfig.LoadBalancingConfig
	// BalancerName represents the load balancer to use.
	BalancerName string
	// ChildPolicy represents the load balancing config for the child
	// policy.
	ChildPolicy *loadBalancingConfig
	// FallBackPolicy represents the load balancing config for the
	// fallback.
	FallBackPolicy *loadBalancingConfig
	// Name to use in EDS query.  If not present, defaults to the server
	// name from the target URI.
	EDSServiceName string
	// LRS server to send load reports to.  If not present, load reporting
	// will be disabled.  If set to the empty string, load reporting will
	// be sent to the same server that we obtained CDS data from.
	LrsLoadReportingServerName string
}

XDSConfig represents the loadBalancingConfig section of the service config for xDS balancers.

func (*XDSConfig) MarshalJSON

func (l *XDSConfig) MarshalJSON() ([]byte, error)

MarshalJSON returns a JSON encoding of l.

func (*XDSConfig) UnmarshalJSON

func (l *XDSConfig) UnmarshalJSON(data []byte) error

UnmarshalJSON parses the JSON-encoded byte slice in data and stores it in l. When unmarshalling, we iterate through the childPolicy/fallbackPolicy lists and select the first LB policy which has been registered.
