_lookup: &mut Self::MetadataLookup,

)
fn row_metadata( _lookup: &mut Self::MetadataLookup, out: &mut Vec<Option<Self::TypeMetadata>>, )
The exact return value of this function is considered to be a
backend specific implementation detail. You should not rely on those
values if you not own the corresponding backend
