Functions

func ConvertToServiceConfig

func ConvertToServiceConfig(lbPolicy *v3clusterpb.LoadBalancingPolicy, depth int) (json.RawMessage, error)

ConvertToServiceConfig converts a proto Load Balancing Policy configuration into a json string. Returns an error if:

• no supported policy found
• there is more than 16 layers of recursion in the configuration
• a failure occurs when converting the policy

func Register

func Register(protoType string, c Converter)

Register registers the converter to the map keyed on a proto type. Must be called at init time. Not thread safe.

func SetRegistry

func SetRegistry(registry map[string]Converter)

SetRegistry sets the xDS LB registry. Must be called at init time. Not thread safe.

Types

type Converter

type Converter func([]byte, int) (json.RawMessage, error)

Converter converts raw proto bytes into the internal Go JSON representation of the proto passed. Returns the json message, and an error. If both returned are nil, it represents continuing to the next proto.
