Struct parquet::file::writer::SerializedRowGroupWriter[−][src]

pub struct SerializedRowGroupWriter<W: ParquetWriter> { /* fields omitted */ }
Expand description

A serialized implementation for Parquet RowGroupWriter. Coordinates writing of a row group with column writers. See documentation on row group writer for more information.

Implementations

impl<W: 'static + ParquetWriter> SerializedRowGroupWriter<W>[src]

pub fn new(
    schema_descr: SchemaDescPtr,
    properties: WriterPropertiesPtr,
    buf: &W
) -> Self[src]

Trait Implementations

impl<W: 'static + ParquetWriter> RowGroupWriter for SerializedRowGroupWriter<W>[src]

fn next_column(&mut self) -> Result<Option<ColumnWriter>>[src]

Returns the next column writer, if available; otherwise returns None. In case of any IO error or Thrift error, or if row group writer has already been closed returns Err. Read more

fn close_column(&mut self, column_writer: ColumnWriter) -> Result<()>[src]

Closes column writer that was created using next_column method. This should be called before requesting the next column writer. Read more

fn close(&mut self) -> Result<RowGroupMetaDataPtr>[src]

Closes this row group writer and returns row group metadata. After calling this method row group writer must not be used. Read more
