Expand description

Combine two shrinkers together element wise into shrinker of tuples.

use monkey_test::*;

let alfa1: BoxShrink<u8> = shrinks::int_to_zero::<u8>();
let beta1: BoxShrink<i64> = shrinks::int_to_zero::<i64>();

let alfa2: BoxShrink<u8> = shrinks::int_to_zero::<u8>();
let beta2: BoxShrink<i64> = shrinks::int_to_zero::<i64>();

// Zip two shrinkers to a tuple shrinker.
let tuples1: BoxShrink<(u8, i64)> = shrinks::zip(alfa1, beta1);

// Shorthand way to do the same thing.
let tuples2: BoxShrink<(u8, i64)> = alfa2.zip(beta2);
