Function malachite_base::iterators::count_is_at_most

pub fn count_is_at_most<I: Iterator>(xs: I, n: usize) -> bool

Returns whether an iterator returns at most some number of values.

count_is_at_most(xs, n) is equivalent to xs.count() <= n for finite iterators, but doesn’t hang if provided an infinite iterator.

Examples

use malachite_base::iterators::count_is_at_most;

assert_eq!(count_is_at_most([1, 2, 3, 4].iter(), 3), false);
assert_eq!(count_is_at_most([1, 2, 3, 4].iter(), 4), true);
assert_eq!(count_is_at_most([1, 2, 3, 4].iter(), 5), true);
