Function itertools::any

pub fn any<I, F>(iterable: I, f: F) -> bool
where
    I: IntoIterator,
    F: FnMut(I::Item) -> bool,

Test whether the predicate holds for any elements in the iterable.

IntoIterator enabled version of i.any(f)

use itertools::any;

assert!(any(&[0, -1, 2], |elt| *elt > 0));
