Function malachite_base::options::random::random_somes

pub const fn random_somes<I: Iterator>(xs: I) -> RandomSomes<I>

Generates random Options except None, with values from a given random iterator.

The values have the same distribution as the values generated by the given iterator: If $Q(x)$ is the probability of $x$ being generated by xs, then

$P(\operatorname{Some}(x)) = Q(x)$.

xs must be infinite.

The output length is infinite.
