Struct OccupiedEntry 

pub struct OccupiedEntry<'a, K, V, S, A, P>
where
    K: Ord,
    P: TreePolicy<K = K, V = V, S = S>,
    A: Allocator,
{ /* private fields */ }

A view into an occupied entry in an AugmentedRBTree.

The entry holds a raw pointer to the existing node, so no key clone is needed.

Implementations

impl<'a, K, V, S, A, P> OccupiedEntry<'a, K, V, S, A, P>

where K: Ord, P: TreePolicy<K = K, V = V, S = S>, A: Allocator,

pub fn key(&self) -> &K

Returns a reference to the key of this entry.

pub fn get(&self) -> &V

Gets a reference to the value in the entry.

pub fn get_mut(&mut self) -> &mut V

Gets a mutable reference to the value in the entry.

pub fn into_mut(self) -> &'a mut V

Converts the OccupiedEntry into a mutable reference to the value in the entry with a lifetime bound to the tree itself.

pub fn insert(&mut self, value: V) -> V

Sets the value of the entry, and returns the old value.

pub fn remove(self) -> V

where K: Clone,

Takes the value out of the entry, and returns it.

Panics

Panics if the tree is corrupted (entry exists but key cannot be found on removal).

Trait Implementations

impl<'a, K, V: Debug, S: Debug, A, P> Debug for OccupiedEntry<'a, K, V, S, A, P>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
