Struct steap_by_steap::priorityqueue::PriorityQueue
source · pub struct PriorityQueue {
heap: BinaryHeap<Reverse<i32>>,
}
Expand description
A priority queue implemented using a binary heap.
Fields§
§heap: BinaryHeap<Reverse<i32>>
Implementations§
source§impl PriorityQueue
impl PriorityQueue
sourcefn push(&mut self, value: i32)
fn push(&mut self, value: i32)
Adds an element to the priority queue.
§Arguments
value
- The integer value to be added to the queue.
sourcefn pop(&mut self) -> Option<i32>
fn pop(&mut self) -> Option<i32>
Removes and returns the smallest element from the priority queue.
§Returns
An Option<i32>
containing the smallest element, or None
if the queue is empty.
sourcefn peek(&self) -> Option<i32>
fn peek(&self) -> Option<i32>
Returns a reference to the smallest element in the priority queue without removing it.
§Returns
An Option<i32>
containing a reference to the smallest element, or None
if the queue is empty.
