Trait grabbag::iter::ZipLongestIterator

pub trait ZipLongestIterator: Iterator + Sized {
    fn zip_longest<RightIt>(self, right: RightIt) -> ZipLongest<Self, RightIt> { ... }
}

(..., a_m), (..., b_m, b_m+1, ..., b_n)  →  ( ..., (Some(a_m), Some(b_m)), (None, Some(b_m+1)), ..., (None, Some(b_n)) )

Provided Methods

fn zip_longest<RightIt>(self, right: RightIt) -> ZipLongest<Self, RightIt>

Creates an iterator which yields elements from both input iterators in lockstep. If one iterator ends before the other, the elements from that iterator will be replaced with None.
