Methods from Deref<Target = Backend<T>>

pub fn append(&mut self, other: &mut LinkedList<T>)

Moves all elements from other to the end of the list.

This reuses all the nodes from other and moves them into self. After this operation, other becomes empty.

This operation should compute in O(1) time and O(1) memory.

Examples

use std::collections::LinkedList;

let mut list1 = LinkedList::new();
list1.push_back('a');

let mut list2 = LinkedList::new();
list2.push_back('b');
list2.push_back('c');

list1.append(&mut list2);

let mut iter = list1.iter();
assert_eq!(iter.next(), Some(&'a'));
assert_eq!(iter.next(), Some(&'b'));
assert_eq!(iter.next(), Some(&'c'));
assert!(iter.next().is_none());

assert!(list2.is_empty());

pub fn iter(&self) -> Iter<'_, T>

Provides a forward iterator.

Examples

use std::collections::LinkedList;

let mut list: LinkedList<u32> = LinkedList::new();

list.push_back(0);
list.push_back(1);
list.push_back(2);

let mut iter = list.iter();
assert_eq!(iter.next(), Some(&0));
assert_eq!(iter.next(), Some(&1));
assert_eq!(iter.next(), Some(&2));
assert_eq!(iter.next(), None);

for element in list.iter_mut() {
    *element += 10;
}

let mut iter = list.iter();
assert_eq!(iter.next(), Some(&10));

where A: Clone,

Splits the list into two at the given index. Returns everything after the given index, including the index.

This operation should compute in O(n) time.

Panics

Panics if at > len.

Examples

use std::collections::LinkedList;

let mut d = LinkedList::new();

pub fn remove(&mut self, at: usize) -> T

🔬This is a nightly-only experimental API. (linked_list_remove)

Removes the element at the given index and returns it.

This operation should compute in O(n) time.

Panics

Panics if at >= len

Examples

#![feature(linked_list_remove)]
use std::collections::LinkedList;

let mut d = LinkedList::new();

d.push_front(1);
d.push_front(2);
d.push_front(3);

assert_eq!(d.remove(1), 2);
assert_eq!(d.remove(0), 3);
assert_eq!(d.remove(0), 1);

pub fn retain<F>(&mut self, f: F)

where F: FnMut(&mut T) -> bool,

🔬This is a nightly-only experimental API. (linked_list_retain)

Retains only the elements specified by the predicate.

In other words, remove all elements e for which f(&mut e) returns false. This method operates in place, visiting each element exactly once in the original order, and preserves the order of the retained elements.

Examples

#![feature(linked_list_retain)]
use std::collections::LinkedList;

let mut d = LinkedList::new();

d.push_front(1);
d.push_front(2);
d.push_front(3);

d.retain(|&mut x| x % 2 == 0);

assert_eq!(d.pop_front(), Some(2));
assert_eq!(d.pop_front(), None);

Because the elements are visited exactly once in the original order, external state may be used to decide which elements to keep.

#![feature(linked_list_retain)]
use std::collections::LinkedList;

let mut d = LinkedList::new();

d.push_front(1);
d.push_front(2);
d.push_front(3);

let keep = [false, true, false];
let mut iter = keep.iter();
d.retain(|_| *iter.next().unwrap());
assert_eq!(d.pop_front(), Some(2));
assert_eq!(d.pop_front(), None);

pub fn extract_if<F>(&mut self, filter: F) -> ExtractIf<'_, T, F, A>

where F: FnMut(&mut T) -> bool,

Creates an iterator which uses a closure to determine if an element should be removed.

If the closure returns true, the element is removed from the list and yielded. If the closure returns false, or panics, the element remains in the list and will not be yielded.

If the returned ExtractIf is not exhausted, e.g. because it is dropped without iterating or the iteration short-circuits, then the remaining elements will be retained. Use extract_if().for_each(drop) if you do not need the returned iterator.

The iterator also lets you mutate the value of each element in the closure, regardless of whether you choose to keep or remove it.

Examples

Splitting a list into even and odd values, reusing the original list:

use std::collections::LinkedList;

let mut numbers: LinkedList<u32> = LinkedList::new();
numbers.extend(&[1, 2, 3, 4, 5, 6, 8, 9, 11, 13, 14, 15]);

let evens = numbers.extract_if(|x| *x % 2 == 0).collect::<LinkedList<_>>();
let odds = numbers;

assert_eq!(evens.into_iter().collect::<Vec<_>>(), vec![2, 4, 6, 8, 14]);
assert_eq!(odds.into_iter().collect::<Vec<_>>(), vec![1, 3, 5, 9, 11, 13, 15]);
