Signature

class baml.csv.Error

A CSV error with positional diagnostics.

kind is for portable handling. line, record, field, and column make "row 41,283 has 7 fields, expected 8" cheap to report.

Every positional field is optional, because not every error has a position: a bad option is caught before parsing starts, and NotFound / TooManyRows are about the input as a whole. They narrow as the failure does — line and record whenever a record is in hand, field and column when one cell is at fault, expected and found only for FieldCount.
