final def emap[B](f: T => Either[String, B]): Decoder[B]

Create a new decoder that performs some operation on the result if this one succeeds.

Decoder
final def ensure(errors: T => List[String]): Decoder[T]

Build a new instance that fails with one or more errors if the condition does not hold for the result.

Build a new instance that fails with one or more errors if the condition does not hold for the result.

If the result of the function applied to the decoded value is the empty list, the new decoder will succeed with that value.

Inherited from
Decoder
final def ensure(pred: T => Boolean, message: => String): Decoder[T]

Build a new instance that fails if the condition does not hold for the result.

Build a new instance that fails if the condition does not hold for the result.

Note that in the case of chained calls to this method, only the first failure will be returned.

final def handleErrorWith(f: DecodingFailure => Decoder[T]): Decoder[T]

Create a new instance that handles any of this instance's errors with the given function.

Create a new instance that handles any of this instance's errors with the given function.

Note that in the case of accumulating decoding, only the first error will be used in recovery.

Decoder
def tryDecode(c: ACursor): Result[T]

Decode the given ACursor.

Decode the given ACursor.

Note that if you override the default implementation, you should also be sure to override tryDecodeAccumulating in order for fail-fast and accumulating decoding to be consistent.
