Struct arrow::ipc::gen::Message::MessageHeader [−][src]
#[repr(transparent)]pub struct MessageHeader(pub u8);
Expand description
The root Message type This union enables us to easily send different message types without redundant storage, and in the future we can easily add new message types.
Arrow implementations do not need to implement all of the message types, which may include experimental metadata types. For maximum compatibility, it is best to send data using RecordBatch
Tuple Fields
