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.

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.

def instance[A](f: Array[Byte] => A): HeaderDeserializer[A]

def string(charset: Charset): HeaderDeserializer[String]

Creates a new HeaderDeserializer which deserializes String values using the specified Charset. Note that the default String deserializer uses UTF-8.

def uuid(charset: Charset): Attempt[UUID]

Creates a new HeaderDeserializer which deserializes String values using the specified Charset as UUIDs. Note that the default UUID deserializer uses UTF-8.

implicit val float: Attempt[Float]
implicit val identity: HeaderDeserializer[Array[Byte]]

implicit val int: Attempt[Int]
implicit val long: Attempt[Long]
implicit val monad: Monad[HeaderDeserializer]
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.
