Struct PriorityQueueItem

pub struct PriorityQueueItem<K, V> {
    pub cost: K,
    pub value: V,
}

Use with BinaryHeap. Since it’s a max-heap, reverse the comparison to get the smallest cost first.

Fields

cost: K

value: V

Trait Implementations

impl<K: Clone, V: Clone> Clone for PriorityQueueItem<K, V>

fn clone(&self) -> PriorityQueueItem<K, V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'de, K, V> Deserialize<'de> for PriorityQueueItem<K, V>

where K: Deserialize<'de>, V: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K: Ord, V: Ord> Ord for PriorityQueueItem<K, V>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<K: PartialEq, V: PartialEq> PartialEq for PriorityQueueItem<K, V>

fn eq(&self, other: &PriorityQueueItem<K, V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<K: Ord, V: Ord> PartialOrd for PriorityQueueItem<K, V>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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

impl<K, V> Serialize for PriorityQueueItem<K, V>

where K: Serialize, V: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
