  5. def map[A](implicit reads: Reads[A]): Reads[Map[String, A]]
  6. def max[O](m: O)(implicit reads: Reads[O], ord: Ordering[O]): Reads[O]

    Defines a maximum value for a Reads.

    Defines a maximum value for a Reads. Combine with min using andKeep, e.g. .read(Reads.min(0.1) andKeep Reads.max(1.0)).

  7. def maxLength[M](m: Int)(implicit reads: Reads[M], p: (M) => Iterable[_]): Reads[M]
  8. def min[O](m: O)(implicit reads: Reads[O], ord: Ordering[O]): Reads[O]

    Defines a minimum value for a Reads.

    Defines a minimum value for a Reads. Combine with max using andKeep, e.g. .read(Reads.min(0) andKeep Reads.max(100)).

  9. def minLength[M](m: Int)(implicit reads: Reads[M], p: (M) => Iterable[_]): Reads[M]
  10. def of[A](implicit r: Reads[A]): Reads[A]

    The simpler of all Reads that just finds an implicit Reads[A] of the expected type

  11. def optionNoError[A](implicit reads: Reads[A]): Reads[Option[A]]

    Stupidly reads a field as an Option mapping any error (format or missing field) to None

  12. def optionWithNull[T](implicit rds: Reads[T]): Reads[Option[T]]

    very simple optional field Reads that maps "null" to None

  13. def pattern(regex: => Regex, error: String = "error.pattern")(implicit reads: Reads[String]): Reads[String]

    Defines a regular expression constraint for String values, i.e.

    Defines a regular expression constraint for String values, i.e. the string must match the regular expression pattern
