Types

type CSVTransformer

type CSVTransformer struct {
	// contains filtered or unexported fields
}

func NewCSVTransformer

func NewCSVTransformer(tablifier Tablifier, cfg CSVTransformerConfig) *CSVTransformer

func (*CSVTransformer) Transform

func (t *CSVTransformer) Transform(ctx context.Context, pages <-chan []byte, w io.Writer) error

type CSVTransformerConfig

type CSVTransformerConfig struct {
	UseHeader bool   // True to use header as a first line
	Delimiter string // Field delimiter (set to ',' by default)
	UseCRLF   bool   // True to use \r\n as the line terminator
}

type DataTransformer

type DataTransformer interface {
	Transform(ctx context.Context, pages <-chan []byte, w io.Writer) error
