module Text.CSV.ByteString

-- | A CSV file is a series of records. According to the RFC, the records
--   all have to have the same length. As an extension, I allow variable
--   length records.
type CSV = [Record]

-- | A record is a series of fields Each record is located on a separate
--   line, delimited by a line break (CRLF).
type Record = [Field]

-- | A field is a strict ByteString. Within the header and each record,
--   there may be one or more ields, separated by commas. Each line should
--   contain the same number of fields throughout the file. Spaces are
--   considered part of a field and should not be ignored. The last field
--   in the record must not be followed by a comma.
type Field = ByteString

-- | Parse a ByteString into a CSV form.
