}Expand description
How to read files, beyond what their extension says: the options of
read_csv(...) and its siblings. None leaves a choice to the extension
or to the session’s defaults.
Fields§
§format: Option<FileFormat>The format, whatever the extension.
compression: Option<CompressionTypeVariant>The compression of CSV or JSON files, whatever the extension.
has_header: Option<bool>CSV: whether the first line is a header.
delimiter: Option<u8>CSV: the field delimiter.
quote: Option<u8>CSV: the quote character.
newline_delimited: Option<bool>JSON: one object per line (true), or one array of objects (false).
