Expand description

Generates random striped Vec<bool>s, with lengths from an iterator.

See here for more information.

The mean run length (before the bit sequences are truncated) is $m$ = mean_stripe_numerator / mean_stripe_denominator.

Panics

Panics if mean_stripe_denominator is zero or if mean_stripe_numerator <= mean_stripe_denominator.
