I guess mp_field_type is just a bad name. It has nothing to do with enum field_type. It just represents all the messagepack types, including the extension types. It helps to eliminate a switch for extension type every time we get an MP_EXT. So, it only deals with mp_type and mp_user_type. > Look at mp_type when you can, and when you get MP_EXT or is > otherwise confused, look at field_type? That’s what I’ve done in previous revision, but Vladimir didn’t like it. And having implemented both variants, I agree that this enum simplifies the code quite a lot. This is especially noticeable with patch 6. So, my proposal is to change the name to something better. value_type? mp_value_type maybe? > > -- > Konstantin Osipov, Moscow, Russia > -- Serge Petrenko sergepetrenko@tarantool.org
