Source 
pub struct OccupiedEntry<'a, TKey, TPriority, S = RandomState>
where
    TKey: 'a + Eq + Hash,
    TPriority: 'a + Ord,
    S: BuildHasher,
{ /* private fields */ }
Expand description

A view into an occupied entry in a KeyedPriorityQueue. It is part of the Entry enum.

Implementations§

Source§

impl<'a, TKey, TPriority, S> OccupiedEntry<'a, TKey, TPriority, S>
where TKey: 'a + Eq + Hash, TPriority: 'a + Ord, S: BuildHasher,

Source

pub fn get_priority(&self) -> &TPriority

§Time complexity

O(1) instant access

Source

pub fn remove(self) -> (TKey, TPriority)

Remove entry from queue

§Time complexity

Up to O(log n) operations
