CellDecoder

fs2.data.csv.CellDecoder
See theCellDecoder companion object

Describes how a cell can be decoded to the given type.

CellDecoder provides convenient methods such as map, emap, or flatMap to build new decoders out of more basic one.

Actually, CellDecoder has a https://typelevel.org/cats/api/cats/MonadError.htmlcats`MonadError` instance. To get the full power of it, import cats.syntax.all._.

Concrete methods

def either[B](cd: CellDecoder[B]): CellDecoder[Either[T, B]]
Implicitly added by decoderResultDecoder

Similar to or, but return the result as an Either signaling which cell decoder succeeded. Allows for parsing an unrelated type in case of failure.
