Struct arrow::ipc::gen::Message::DictionaryBatch [−][src]
pub struct DictionaryBatch<'a> { pub _tab: Table<'a>, }
Expand description
For sending dictionary encoding information. Any Field can be dictionary-encoded, but in this case none of its children may be dictionary-encoded. There is one vector / column per dictionary, but that vector / column may be spread across multiple dictionary batches by using the isDelta flag
Fields
_tab: Table<'a>
