final case class GenericRecordParseIO[T](path: String, parseFn: (GenericRecord) ⇒ T)(implicit coder: Coder[T]) extends AvroIO[T] with Product with Serializable

Given a parseFn, read GenericRecord and apply a function mapping => T before producing output. This IO applies the function at the time of de-serializing Avro GenericRecords.

This IO doesn't define write, and should not be used to write Avro GenericRecords.
