Overview

Package internal contains gRPC-internal code, to avoid polluting the godoc of the top-level grpc package. It must not import any grpc symbols to avoid circular dependencies.

const RLSLoadBalancingPolicyName = "rls_experimental"

RLSLoadBalancingPolicyName is the name of the RLS LB policy.

It currently has an experimental suffix which would be removed once end-to-end testing of the policy is completed.

Functions

func GetXDSHandshakeClusterName added in v1.38.0

func GetXDSHandshakeClusterName(attr *attributes.Attributes) (string, bool)

GetXDSHandshakeClusterName returns cluster name stored in attr.

func SetXDSHandshakeClusterName added in v1.38.0

func SetXDSHandshakeClusterName(addr resolver.Address, clusterName string) resolver.Address

SetXDSHandshakeClusterName returns a copy of addr in which the Attributes field is updated with the cluster name.

Types

type HealthChecker added in v1.18.0

type HealthChecker func(ctx context.Context, newStream func(string) (interface{}, error), setConnectivityState func(connectivity.State, error), serviceName string) error

HealthChecker defines the signature of the client-side LB channel health checking function.

The implementation is expected to create a health checking RPC stream by calling newStream(), watch for the health status of serviceName, and report it's health back by calling setConnectivityState().

The health checking protocol is defined at: https://github.com/grpc/grpc/blob/master/doc/health-checking.md
