Struct DirectPathPieceBuffer 

pub struct DirectPathPieceBuffer { /* private fields */ }

Streaming encoder for the direct path column-array piece format.

Port of the reference PieceBuffer (direct_path_load_stream.pyx). Usage: start_row() / add_column_value(..) per column / finish_row(), then DirectPathPieceBuffer::finish.

Implementations

impl DirectPathPieceBuffer

pub fn new() -> Self

pub fn start_row(&mut self) -> Result<()>

pub fn finish_row(&mut self) -> Result<()>

pub fn add_column_value( &mut self, metadata: &ColumnMetadata, value: &DirectPathColumnValue, row_num: u64, ) -> Result<()>

pub fn finish(self) -> Result<(Vec<DirectPathPiece>, u32)>

Finalizes the stream and returns the pieces plus the total piece length (piece data plus piece headers) for the load stream message.

Trait Implementations

impl Debug for DirectPathPieceBuffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DirectPathPieceBuffer

fn default() -> DirectPathPieceBuffer

Returns the “default value” for a type.
