def apply[A](implicit deserializer: HeaderDeserializer[A]): HeaderDeserializer[A]
def attempt[A](implicit deserializer: Attempt[A]): Attempt[A]
def const[A](a: A): HeaderDeserializer[A]

Creates a new HeaderDeserializer which deserializes all bytes to the specified value of type A.

def delegate[A](deserializer: Deserializer[A]): HeaderDeserializer[A]

Creates a new HeaderDeserializer which delegates deserialization to the specified Kafka Deserializer. Please note that the close and configure functions won't be called for the delegate. Also, the topic is an empty String and no headers are provided.

Implicits

Implicits

implicit val identity: HeaderDeserializer[Array[Byte]]

The identity HeaderDeserializer, which does not perform any kind of deserialization, simply using the input bytes as the output.

Source:
HeaderDeserializer.scala
implicit def option[A](implicit deserializer: HeaderDeserializer[A]): HeaderDeserializer[Option[A]]

The option HeaderDeserializer returns None when the bytes are null, and otherwise deserializes using the deserializer for the type A, wrapping the result in Some.
