trait JsonDecoder[A] extends JsonDecoderPlatformSpecific[A]

A JsonDecoder[A] instance has the ability to decode JSON to values of type A, potentially failing with an error if the JSON content does not encode a value of the given type.

    Returns a new codec that combines this codec and the specified codec using fallback semantics: such that if this codec fails, the specified codec will be tried instead. This method may be unsafe from a security perspective: it can use more memory than hand coded alternative and so lead to DOS.

    For example, in the case of an alternative between Int and Boolean, a hand coded alternative would look like:

    val decoder: JsonDecoder[AnyVal] = JsonDecoder.peekChar[AnyVal] { case 't' | 'f' => JsonDecoder[Boolean].widen case c => JsonDecoder[Int].widen }

  31. final def orElseEither[B](that: => JsonDecoder[B]): JsonDecoder[Either[A, B]]
