final case class Gen[-R, +A](sample: ZStream[R, Nothing, Sample[R, A]]) extends Product with Serializable

  8. def collect[B](pf: PartialFunction[A, B])(implicit trace: Trace): Gen[R, B]

    Maps the values produced by this generator with the specified partial function, discarding any values the partial function is not defined at.

  9. def concat[R1 <: R, A1 >: A](that: Gen[R1, A1])(implicit trace: Trace): Gen[R1, A1]

    Concatenates the specified deterministic generator with this determinstic generator, resulting in a deterministic generator that generates the values from this generator and then the values from the specified generator.

  10. final def eq(arg0: AnyRef): Boolean
    Definition Classes
    AnyRef
  11. def filter(f: (A) ⇒ Boolean)(implicit trace: Trace): Gen[R, A]

    Filters the values produced by this generator, discarding any values that do not meet the specified predicate.

    Filters the values produced by this generator, discarding any values that do not meet the specified predicate. Using filter can reduce test performance, especially if many values must be discarded. It is recommended to use combinators such as map and flatMap to create generators of the desired values instead.

    val evens: Gen[Any, Int] = Gen.int.map(_ * 2)
  12. def filterNot(f: (A) ⇒ Boolean)(implicit trace: Trace): Gen[R, A]

    Filters the values produced by this generator, discarding any values that meet the specified predicate.

  24. def reshrink[R1 <: R, B](f: (A) ⇒ Sample[R1, B])(implicit trace: Trace): Gen[R1, B]

    Discards the shrinker for this generator and applies a new shrinker by mapping each value to a sample using the specified function.

    Discards the shrinker for this generator and applies a new shrinker by mapping each value to a sample using the specified function. This is useful when the process to shrink a value is simpler than the process used to generate it.

  25. def resize(size: Int)(implicit trace: Trace): Gen[R, A]

    Sets the size parameter for this generator to the specified value.

  26. def runCollect(implicit trace: Trace): ZIO[R, Nothing, List[A]]

    Runs the generator and collects all of its values in a list.

  27. def runCollectN(n: Int)(implicit trace: Trace): ZIO[R, Nothing, List[A]]

    Repeatedly runs the generator and collects the specified number of values in a list.

  28. def runHead(implicit trace: Trace): ZIO[R, Nothing, Option[A]]

    Runs the generator returning the first value of the generator.
