Struct PreparedUint8Ipc

Source

pub struct PreparedUint8Ipc { /* private fields */ }

Expand description

A prepared no-null UInt8 IPC fast-path encode.

The UInt8 construct-in-place path (used by send_output_raw and the Python buffer-protocol send) sizes the sample from the layout and then writes the header into it. Both steps need [uint8_layout], which builds the schema + record-batch flatbuffer headers. This handle computes the layout once and reuses it for both, instead of the double build a separate uint8_ipc_len + encode_uint8_ipc_header pair incurs.
