func RegisterReplicationServiceHandler added in v2.146.0 

func RegisterReplicationServiceHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterReplicationServiceHandler registers the http handlers for service ReplicationService to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterReplicationServiceHandlerClient added in v2.146.0 

func RegisterReplicationServiceHandlerClient(ctx context.Context, mux *runtime.ServeMux, client ReplicationServiceClient) error

RegisterReplicationServiceHandlerClient registers the http handlers for service ReplicationService to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "ReplicationServiceClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "ReplicationServiceClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "ReplicationServiceClient" to call the correct interceptors.

func RegisterReplicationServiceHandlerFromEndpoint added in v2.146.0 

func RegisterReplicationServiceHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterReplicationServiceHandlerFromEndpoint is same as RegisterReplicationServiceHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterReplicationServiceHandlerServer added in v2.146.0 

func RegisterReplicationServiceHandlerServer(ctx context.Context, mux *runtime.ServeMux, server ReplicationServiceServer) error

RegisterReplicationServiceHandlerServer registers the http handlers for service ReplicationService to "mux". UnaryRPC :call ReplicationServiceServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features to stop working. Consider using RegisterReplicationServiceHandlerFromEndpoint instead.

func RegisterReplicationServiceServer added in v2.146.0
