Ajaxdone
I run into the issue at runtime, the usage of enum in protobuf generated code looks not right, Here is the code, but I don’t know how to use it, any idea? :
defmodule HelloPhx.ServiceType do
@moduledoc false
use Protobuf, enum: true, syntax: :proto3
@type t :: integer | :LOGIN | :REFRESH_TOKEN
field :LOGIN, 0
field :REFRESH_TOKEN, 1
end
Here is the error:
[error] ** (Protobuf.EncodeError) Got error when encoding Hellophx.TokenReply#s_type: ** (ArithmeticError) bad argument in arithmetic expression
I just used like this: HelloPhx.ServiceType.LOGIN 
But not working, any idea?
