}

Expand description

Options for writing CSV files

Fields§

§writer_options: WriterBuilder

Struct from the arrow crate which contains all csv writing related settings

§compression: CompressionTypeVariant

Compression to apply after ArrowWriter serializes RecordBatches. This compression is applied by DataFusion not the ArrowWriter itself.

§compression_level: Option<u32>

Compression level for the output file.
