lib.rs:

This crate provides an iterator that pads the end of the iterator with a value up to a given length.

Examples:

use padded_iterator::PaddedIterBuilder;

let mut iter = PaddedIterBuilder::new()
    .iter(vec![1, 2, 3].into_iter())
    .length(5)
    .pad(0)
    .build()
    .unwrap();

assert_eq!(iter.next(), Some(1));
assert_eq!(iter.next(), Some(2));
assert_eq!(iter.next(), Some(3));
assert_eq!(iter.next(), Some(0));
assert_eq!(iter.next(), Some(0));
assert_eq!(iter.next(), None);

use padded_iterator::PaddedIter;

let mut iter = PaddedIter::from((vec![1, 2, 3].into_iter(), 5, 0));

assert_eq!(iter.next(), Some(1));
assert_eq!(iter.next(), Some(2));
assert_eq!(iter.next(), Some(3));
assert_eq!(iter.next(), Some(0));
assert_eq!(iter.next(), Some(0));
assert_eq!(iter.next(), None);
