Documentation

data CSVError

Codec error type.

Constructors

IncompleteCell

Input ends in a partial cell value. For encoder, this means that the last Cell of the input stream specifies the EOP delimiter instead of EOR or EOT. For decoder, this means that the last cell of the input stream is missing the closing quote character.

IncompleteRow

Input ends in a partial row value. For encoder, this means that the last Cell of the input stream specifies the EOC delimiter instead of EOR or EOT. For decoder, this means that the last row of the input stream is missing the line break sequence.
