CsvSourceOps

final class CsvSourceOps[A] extends AnyRef

Provides useful syntax for types that have implicit instances of CsvSource in scope.

The most common use case is to turn a value into a CsvReader:

scala> import kantan.csv._

scala> "1,2,3\n4,5,6".asCsvReader[List[Int]](rfc).toList
res0: List[ReadResult[List[Int]]] = List(Right(List(1, 2, 3)), Right(List(4, 5, 6)))

A slightly less common use case is to load an entire CSV file in memory:

scala> "1,2,3\n4,5,6".readCsv[List, List[Int]](rfc)
res1: List[ReadResult[List[Int]]] = List(Right(List(1, 2, 3)), Right(List(4, 5, 6)))

Unsafe versions of these methods are also available, even if usually advised against.
