trait CellDecoder[T] extends AnyRef
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._.

Similar to or, but return the result as an Either signaling which cell decoder succeeded.
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.
- B
the type the alternative decoder returns
- cd
the alternative decoder
- returns
a decoder combining both decoders

Fail-over.
Fail-over. If this decoder fails, try the supplied other decoder.
- TT
the return type

- returns
a decoder combining this and the other decoder
