Hi all,
Consider the example (from the grpc docs) service definition below:
service Greeter {
// Sends a greeting
rpc SayHello (HelloRequest) returns (HelloReply) {}
}
What is the {} at the end in the declaration of SayHello required for? It
seems optional, since the example in the proto3 spec
(https://developers.google.com/protocol-buffers/docs/reference/proto3-spec)
doesn't use it.
Thank you in advance.
Best Wishes,
Amit.
