func NewCsvQuoteState

func NewCsvQuoteState() *CsvQuoteState

func (*CsvQuoteState) DecodeString

func (c *CsvQuoteState) DecodeString(value string, quoteSymbol rune) string

Decodes a string value.

Parameters:

• value: A string value to be decoded.
• quoteSymbol: A string quote character.

Returns: An decoded string.

func (*CsvQuoteState) EncodeString

func (c *CsvQuoteState) EncodeString(value string, quoteSymbol rune) string

Encodes a string value.

Parameters:

• value: A string value to be encoded.
