Proxy_ServiceDesc is the grpc.ServiceDesc for Proxy service. It's only intended for direct use with grpc.RegisterService, and not to be introspected or modified (even as a copy)

Functions

Types

type ClientCancel 

type ClientCancel struct {

	// The server-assigned stream id(s) to cancel.
	StreamIds []uint64 `protobuf:"varint,1,rep,packed,name=stream_ids,json=streamIds,proto3" json:"stream_ids,omitempty"`
	// contains filtered or unexported fields
}

ClientCancel is sent by the proxy client to request cancellation of the given stream(s).

func (*ClientCancel) Descriptor deprecated
