Function iter_set::difference [−][src]
pub fn difference<T, L, R>(a: L, b: R) -> impl Iterator<Item = T> where
T: Ord,
L: IntoIterator<Item = T>,
R: IntoIterator<Item = T>,
Expand description
Take the difference of two sets (elements in a
but not in b
) represented by sorted,
deduplicated iterators.
Time complexity: O(a.len() + b.len())
.
Examples
use iter_set::difference;
let a = [1, 2];
let b = [2, 3];
assert!(difference(&a, &b).eq(&[1]));
