Sample

final case class Sample[-R, +A](value: A, shrink: ZStream[R, Nothing, Option[Sample[R, A]]])

A sample is a single observation from a random variable, together with a tree of "shrinkings" used for minimization of "large" failures.

Concrete methods

def <*>[R1 <: R, B](that: Sample[R1, B])(implicit zippable: Zippable[A, B], trace: Trace): Sample[R1, Out]

A symbolic alias for zip.

A symbolic alias for zip.

def filter(f: A => Boolean)(implicit trace: Trace): ZStream[R, Nothing, Option[Sample[R, A]]]

Filters this sample by replacing it with its shrink tree if the value does not meet the specified predicate and recursively filtering the shrink tree.

Filters this sample by replacing it with its shrink tree if the value does not meet the specified predicate and recursively filtering the shrink tree.

def flatMap[R1 <: R, B](f: A => Sample[R1, B])(implicit trace: Trace): Sample[R1, B]
def foreach[R1 <: R, B](f: A => ZIO[R1, Nothing, B])(implicit trace: Trace): ZIO[R1, Nothing, Sample[R1, B]]
def map[B](f: A => B)(implicit trace: Trace): Sample[R, B]
def shrinkSearch(f: A => Boolean)(implicit trace: Trace): ZStream[R, Nothing, A]

Converts the shrink tree into a stream of shrinkings by recursively searching the shrink tree, using the specified function to determine whether a value is a failure. The resulting stream will contain all values explored, regardless of whether they are successes or failures.

def zip[R1 <: R, B](that: Sample[R1, B])(implicit zippable: Zippable[A, B], trace: Trace): Sample[R1, Out]

Composes this sample with the specified sample to create a cartesian product of values and shrinkings.

Composes this sample with the specified sample to create a cartesian product of values and shrinkings.

def zipWith[R1 <: R, B, C](that: Sample[R1, B])(f: (A, B) => C)(implicit trace: Trace): Sample[R1, C]

Composes this sample with the specified sample to create a cartesian product of values and shrinkings with the specified function.
