Describes how a row can be decoded to the given type.
RowDecoderF provides convenient methods such as map, emap, or flatMap to build new decoders out of more basic one.
Actually, RowDecoderF has a cats 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 row decoder succeeded.
Similar to or, but return the result as an Either signaling which row decoder succeeded. Allows for parsing an unrelated type in case of failure.
