Struct mz_repr::row::ProtoDatum
source · [−]Fields
datum_type: Option<DatumType>
NB: Proto oneof ids 1..=15
get encoded in 1 byte and so we should
reserve them for the datum types we expect to be most popular.
Null, False, and True are all likely to be frequent, but the encoded length is exactly the same if they’re here or in ProtoDatumOther. In general, anything that can be encoded purely as a proto enum variant (i.e. doesn’t have a payload) is better off that way. If we run out of 1-byte encodings of ProtoDatumOther, we can always add ProtoDatumOther2.
