Inspect a generator or disable its shrinking — gen

gen_example() draws one value at a fixed size with a local seed, restoring the caller's RNG kind and state on exit, as check_law() does. It does not expand the shrink tree. gen_no_shrink() keeps generation unchanged but removes all shrink candidates, including those carried by composed generators.

Usage

gen_example(generator, size = 10L, seed = 1L)

gen_no_shrink(generator)

Arguments

generator: A generator.
size: Non-negative integer size.
seed: Integer seed for reproducible generation.

Value

gen_example() returns one generated value. gen_no_shrink() returns an S7 generator object with the original element prototype.

Examples

gen_example(gen_vector(gen_integer()), size = 5L, seed = 42L)
#> integer(0)
