Struct ZipLongest

#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct ZipLongest<T, U> { /* private fields */ }

An iterator which iterates two other iterators simultaneously and wraps the elements in EitherOrBoth.

This iterator is fused.

See .zip_longest() for more information.
