HeaderDecoder

kantan.csv.HeaderDecoder
See theHeaderDecoder companion object
trait HeaderDecoder[A] extends Serializable

Provides support for using header values rather than row indexes for decoding.

When decoding CSV data, if the CsvConfiguration indicates the presence of a header, it will be passed to fromHeader, and the resulting RowDecoder will be used.

The default behaviour is always to rely on indexes (that is, any instance of RowDecoder that might be available), but you can create more useful HeaderDecoder instances through the companion object.

Combines two header decoders creating a tupled version that will decode the results from both. The combination will preserve the order of the merge in the case that no headers are detected.
