Struct hopscotch::ItemMut

pub struct ItemMut<'a, K, V> { /* fields omitted */ }

A mutable reference to an item currently in the queue.

Implementations

impl<'a, K: Ord, V> ItemMut<'a, K, V>

pub fn index(&self) -> u64

The index of the item: this is unique for the entire lifetime of the queue from which this item originated.

pub fn tag(&self) -> &K

The tag of the item which was originally assigned when the item was inserted into the queue.

pub fn value_mut(&mut self) -> &mut V

Get a mutable reference to the value contained in this item.

pub fn into_mut(self) -> &'a mut V

Extract a mutable reference to the value whose lifetime is tied to the entire queue, not this Item.

impl<'a, K: Ord, V: Ord> Ord for ItemMut<'a, K, V>

fn cmp(&self, other: &ItemMut<'a, K, V>) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl<'a, K: PartialEq, V: PartialEq> PartialEq<ItemMut<'a, K, V>> for ItemMut<'a, K, V>

fn eq(&self, other: &ItemMut<'a, K, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ItemMut<'a, K, V>) -> bool

This method tests for !=.

impl<'a, K: PartialOrd, V: PartialOrd> PartialOrd<ItemMut<'a, K, V>> for ItemMut<'a, K, V>

fn partial_cmp(&self, other: &ItemMut<'a, K, V>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &ItemMut<'a, K, V>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &ItemMut<'a, K, V>) -> bool

fn gt(&self, other: &ItemMut<'a, K, V>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &ItemMut<'a, K, V>) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
