Struct RefMut

Source
pub struct RefMut<'a, K: 'a + Hash + Eq, T: 'a, C: 'a + Compare<T>> { /* private fields */ }
Expand description

Structure wrapping a mutable reference to any item on a BinaryHeap.

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

Implementations§

Source§

impl<K: Hash + Eq, T, C: Compare<T>> RefMut<'_, K, T, C>

Source

pub fn key(&self) -> &K

returns the key of the heap item.

Source

pub fn key_value(&self) -> (&K, &T)

returns a key-value pair for this heap item.

Source

pub fn key_value_mut(&mut self) -> (&K, &mut T)

returns a mutable key-value pair for this heap item. modifying the key is not possible. Only the value is mutable.
