WebThe gRPC server listens to connection requests from clients at the gRPC service port. 2. A user runs a gRPC client application to log in to the gRPC server. 3. The gRPC client calls methods provided in the .proto file to send requests. For more information about .proto files, see "Proto files." 4. WebField presence is the notion of whether a protobuf field has a value. There are two different manifestations of presence for protobufs: no presence, where the generated message API stores field values (only), and explicit presence, where the API also stores whether or not a field has been set.
