Expand description

Options for CSV decoding.

Fields§

§delimiter: u8

Delimiter (e.g., b’,’ for CSV, b’\t’ for TSV).

§nulls: Vec<&'static str>

String(s) that should be parsed as nulls.

§quote: u8

Quote character to use (default: ‘“’).

§has_header: bool

Whether to use the first row as a header.

§schema: Option<Vec<Field>>

Optional schema. If None, schema is inferred.

§all_as_text: bool

If true, all columns are loaded as String32.

§categorical_cols: HashSet<String>

For categoricals: columns that should be parsed as categorical.
