grpc v0.3.0-alpha.1 GRPC.Server
A gRPC server which handles requests by calling user-defined functions.
You should pass a GRPC.Service
in when use the module:
defmodule Greeter.Service do
use GRPC.Service, name: "ping"
rpc :SayHello, Request, Reply
rpc :SayGoodbye, stream(Request), stream(Reply)
end
defmodule Greeter.Server do
use GRPC.Server, service: Greeter.Service
def say_hello(request, _stream) do
Reply.new(message: "Hello")
end
def say_goodbye(request_enum, stream) do
requests = Enum.map request_enum, &(&1)
GRPC.Server.send_reply(stream, reply1)
GRPC.Server.send_reply(stream, reply2)
end
end
Your functions should accept a client request and a GRPC.Server.Stream
.
The request will be a Enumerable.t
(created by Elixir’s Stream
) of requests
if it’s streaming. If a reply is streaming, you need to call send_reply/2
to send
replies one by one instead of returning reply in the end.
For most functions which return stream, you MUST use the new stream as argument of other functions in this module. And you MUST return that stream in the end in your rpc functions.
