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

Maps an effectual function over a generator.
Maps an effectual function over a generator.
Attributes
Discards the shrinker for this generator.
Discards the shrinker for this generator.
Attributes
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.
