And as for why nanopb is the only one encoding it differently, it is because I always encode as packed. (Listed under limitations here http://koti.kapsi.fi/jpa/nanopb/docs/index.html ) This design choice was made because parsers should be able to decode both types, and packed format is more efficient for arrays longer than 1. So from code size point of view it didn't make sense to implement both formats. It may be that ProtoBuf.jl has just overlooked this point that decoders should accept both formats. As a workaround, one can try adding [packed=true] to .proto. -- Petteri -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
