Function malachite_base::iterators::count_is_at_least

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

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

count_is_at_least(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_least;

assert_eq!(count_is_at_least([1, 2, 3, 4].iter(), 3), true);
assert_eq!(count_is_at_least([1, 2, 3, 4].iter(), 4), true);
assert_eq!(count_is_at_least([1, 2, 3, 4].iter(), 5), false);
assert_eq!(count_is_at_least(0.., 5), true);
