impl<T> LinkedList<T>

const: 1.39.0 · source

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

Removes the element at the given index and returns it.

§Examples

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

let mut d = LinkedList::new();

d.push_front(1);

pub fn retain<F>(&mut self, f: F)
where F: FnMut(&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(&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(|&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 retain_mut<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(&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| if *x % 2 == 0 {
    *x += 1;
    true
} else {
    false
});
assert_eq!(d.pop_front(), Some(3));
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,

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

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

If the closure returns true, then the element is removed and yielded. If the closure returns false, the element will remain in the list and will not be yielded by the iterator.

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.

Note that extract_if lets you mutate every element in the filter closure, regardless of whether you choose to keep or remove it.

§Examples

Splitting a list into evens and odds, reusing the original list:

#![feature(extract_if)]
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]);
