Struct std::collections::binary_heap::PeekMut

pub struct PeekMut<'a, T> where
    T: 'a + Ord + 'a,  { /* fields omitted */ }

Structure wrapping a mutable reference to the greatest item on a BinaryHeap.

This struct is created by the peek_mut method on BinaryHeap. See its documentation for more.

Methods

impl<'a, T> PeekMut<'a, T> where
    T: Ord, 

pub fn pop(this: PeekMut<'a, T>) -> T

Removes the peeked value from the heap and returns it.
