Struct collections::linked_list::IterMut1.0.0 [] [src]

pub struct IterMut<'a, T> where
    T: 'a, 
{ /* fields omitted */ }

A mutable iterator over the elements of a LinkedList.

This struct is created by the iter_mut method on LinkedList. See its documentation for more.

Methods

impl<'a, T> IterMut<'a, T>
[src]

[src]

🔬 This is a nightly-only experimental API. (linked_list_extras #27794)

this is probably better handled by a cursor type -- we'll see

Inserts the given element just after the element most recently returned by .next(). The inserted element does not appear in the iteration.

Examples

#![feature(linked_list_extras)]

use std::collections::LinkedList;

let mut list: LinkedList<_> = vec![1, 3, 4].into_iter().collect();

{
    let mut it = list.iter_mut();
    assert_eq!(it.next().unwrap(), &1);
    // insert `2` after `1`
    it.insert_next(2);
}
{
    let vec: Vec<_> = list.into_iter().collect();
    assert_eq!(vec, [1, 2, 3, 4]);
}

🔬 This is a nightly-only experimental API. (linked_list_extras #27794)

this is probably better handled by a cursor type -- we'll see

Provides a reference to the next element, without changing the iterator.

Examples

#![feature(linked_list_extras)]

use std::collections::LinkedList;

let mut list: LinkedList<_> = vec![1, 2, 3].into_iter().collect();

let mut it = list.iter_mut();
assert_eq!(it.next().unwrap(), &1);
assert_eq!(it.peek_next().unwrap(), &2);
// We just peeked at 2, so it was not consumed from the iterator.
assert_eq!(it.next().unwrap(), &2);
