Hello,

I'm receiving protobuf messages from a client (I can't modify them in any 
way) with a list of hotels. There are hotels in the 90% of the times, but I 
need to differentitate when I receive hotels and when not.

The proto file for "no hotels" is something like below (simplified):
1: {
1: {}
2: {}
}

Is there any way to check the "2:" element is empty without loading the 
whole proto into memory?

Thanks,

Joan.
