oneof is a property of the message that the fields are in; it's not really
a type of its own. Instead, you could do something like
message Event {
required int32 event_id = 1;
optional EventSpecifics specifics = 2;
}
message EventSpecifics {
oneof EventType {
optional FooEvent foo_event = 1;
optional BarEvent bar_event = 2;
}
}
