Struct PaddedIter

pub struct PaddedIter<T: Iterator<Item = U>, U> { /* private fields */ }

An iterator which has been padded to a given length.

Implementations

impl<T, U> PaddedIter<T, U>

where T: Iterator<Item = U>, U: Clone,

pub fn next(&mut self) -> Option<U>

Trait Implementations

impl<T: Debug + Iterator<Item = U>, U: Debug> Debug for PaddedIter<T, U>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, U> From<(T, usize, U)> for PaddedIter<T, U>

where T: Iterator<Item = U>, U: Clone,

fn from((iter, length, pad): (T, usize, U)) -> Self

Create a new PaddedIter from an iterator, length, and pad value.

Examples:

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);
