// Request describes the request header sent by the client to the server.  A
// non-zero request header is sent at the beginning of the RPC call, followed by
// the positional args.  Thereafter a zero request header is sent before each
// streaming arg, terminated by a non-zero request header with EndStreamArgs set
// to true.
type Request struct {
	// Suffix of the name used to identify the object hosting the service.
	Suffix string
	// Method to invoke on the service.
	Method string
	// NumPosArgs is the number of positional arguments, which follow this message
	// (and any blessings) on the request stream.
	NumPosArgs uint64
	// EndStreamArgs is true iff no more streaming arguments will be sent.  No
	// more data will be sent on the request stream.
	//
	// NOTE(bprosnitz): We can support multiple stream values per request (+response) header
	// efficiently by adding a NumExtraStreamArgs (+NumExtraStreamResults to response) field
	// that is the uint64 (number of stream args to send) - 1. The request is then zero when
	// exactly one streaming arg is sent. Since the request and response headers are small,
	// this is only likely necessary for frequently streaming small values.
	// See implementation in CL: 3913
	EndStreamArgs bool
	// Deadline after which the request should be cancelled.  This is a hint to
	// the server, to avoid wasted work.
	Deadline time.Deadline
	// GrantedBlessings are blessings bound to the principal running the server,
	// provided by the client.
	GrantedBlessings security.Blessings
	// TraceRequest maintains the vtrace context between clients and servers
	// and specifies additional parameters that control how tracing behaves.
	TraceRequest vtrace.Request
	// Language indicates the language of the instegator of the RPC.
	// By convention it should be an IETF language tag:
	// http://en.wikipedia.org/wiki/IETF_language_tag
