Hi all
When I was reading guides for protobuf 3, there was a huge limitation for
oneof field. The guide states that updating a message by adding new fields
to an existing oneof field is not safe. For example, if I have following
message:
message TestIt {
oneof my_field {
DataA a = 1;
DataB b = 2;
}
}
I cannot update it to the this new message:
message TestIt {
oneof my_field {
DataA a = 1;
DataB b = 2;
DataC c = 3;
}
}
I think this is a really huge limitation for oneof field and makes it
useless in a lot of cases. Is there any way to achieve something similar
without using Any object?
