Interface exported by the server.

• rpc GetFeature (Point, Feature)

  route_guide.proto:31

  A simple RPC. Obtains the feature at a given position. A feature with an empty name is returned if there's no feature at the given position.

• rpc ListFeatures (Rectangle, stream Feature)

  route_guide.proto:39

  A server-to-client streaming RPC. Obtains the Features available within the given Rectangle. Results are streamed rather than returned at once (e.g. in a response message with a repeated field), as the rectangle may cover a large area and contain a huge number of features.

  message Rectangle

  route_guide.proto:75

  A latitude-longitude rectangle, represented as two diagonally opposite points "lo" and "hi".

  • optional Point lo = 1

    One corner of the rectangle.

  • optional Point hi = 2

    The other corner of the rectangle.

• rpc RecordRoute (stream Point, RouteSummary)

  route_guide.proto:45

  A client-to-server streaming RPC. Accepts a stream of Points on a route being traversed, returning a RouteSummary when traversal is completed.

  message RouteSummary

  route_guide.proto:108

  A RouteSummary is received in response to a RecordRoute rpc. It contains the number of individual points received, the number of detected features, and the total distance covered as the cumulative sum of the distance between each point.

  • int32 point_count = 1

    The number of points received.

  • int32 feature_count = 2

    The number of known features passed while traversing the route.

  • int32 distance = 3

    The distance covered in metres.

  • int32 elapsed_time = 4

    The duration of the traversal in seconds.

• rpc RouteChat (stream RouteNote, stream RouteNote)

  route_guide.proto:51

  A Bidirectional streaming RPC. Accepts a stream of RouteNotes sent while a route is being traversed, while receiving other RouteNotes (e.g. from other users).

  message RouteNote

  route_guide.proto:95

  A RouteNote is a message sent while at a given point.

  • optional Point location = 1

    The location from which the message is sent.

  • string message = 2

    The message to be sent.

• rpc GenerateError (Empty, Empty)

  route_guide.proto:54

  A simple RPC, which always generates error response.

• rpc StreamingGenerateError (Empty, stream Empty)

  route_guide.proto:57

  A simple RPC, which always generates error response.

Empty message - use for RPCs without input or output.

Used as request type in: RouteGuide.GenerateError, RouteGuide.StreamingGenerateError

Used as response type in: RouteGuide.GenerateError, RouteGuide.StreamingGenerateError

(message has no fields)

A feature names something at a given point. If a feature could not be named, the name is empty.

Used as response type in: RouteGuide.GetFeature, RouteGuide.ListFeatures

• string name = 1

  The name of the feature.

• optional Point location = 2

  The point where the feature is detected.

Points are represented as latitude-longitude pairs in the E7 representation (degrees multiplied by 10**7 and rounded to the nearest integer). Latitudes should be in the range +/- 90 degrees and longitude should be in the range +/- 180 degrees (inclusive).

Used as request type in: RouteGuide.GetFeature, RouteGuide.RecordRoute

Used as field type in: Feature, Rectangle, RouteNote

• int32 latitude = 1

• int32 longitude = 2
