Types

type LBConfig

type LBConfig 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
}

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

func (*LBConfig) MarshalJSON

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

MarshalJSON returns a JSON enconding of l.

func (*LBConfig) UnmarshalJSON

func (l *LBConfig) 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.

type LoadBalancingConfig

type LoadBalancingConfig struct {
	Name   string
	Config json.RawMessage
}

LoadBalancingConfig represents a single load balancing config, stored in JSON format.

func (*LoadBalancingConfig) MarshalJSON

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

MarshalJSON returns a JSON enconding of l.

func (*LoadBalancingConfig) UnmarshalJSON

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

UnmarshalJSON parses the JSON-encoded byte slice in data and stores it in l.

type Locality

type Locality struct {
	Region  string
	Zone    string
	SubZone string
}

Locality 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.

This struct should only be used as map keys. Use the proto message directly in all other places.

func (Locality) String

func (lamk Locality) String() string

func (Locality) ToProto

func (lamk Locality) ToProto() *basepb.Locality

ToProto convert Locality to the proto representation.
