Struct OccupiedEntry 

pub struct OccupiedEntry<'a, 's, A: Allocator, K: PartialOrd + Debug, V, B: ArrayLength>
where
    U2: Mul<B>,
    Prod<U2, B>: ArrayLength,
    U1: Add<Prod<U2, B>>,
    Sum<U1, Prod<U2, B>>: ArrayLength,
{ /* private fields */ }

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

Implementations

impl<'a, 's, A: Allocator, K: PartialOrd + Debug, V, B: ArrayLength> OccupiedEntry<'a, 's, A, K, V, B>

where U2: Mul<B>, Prod<U2, B>: ArrayLength, U1: Add<Prod<U2, B>>, Sum<U1, Prod<U2, B>>: ArrayLength,

pub fn key(&self) -> &K

Gets a reference to the key in the entry.

pub fn key_below(&self) -> Option<&K>

Returns a reference to the key that is immediately below (predecessor of) this occupied entry’s key in the tree’s sorted order. Returns None if this entry is the minimum key.

pub fn key_above(&self) -> Option<&K>

Returns a reference to the key that is immediately above (successor of) this occupied entry’s key in the tree’s sorted order. Returns None if this entry is the maximum key.

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) -> &'s mut V

Converts the entry into a mutable reference to its value.

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

Sets the value of the entry with the OccupiedEntry’s key, and returns the entry’s old value.

pub fn remove(self) -> V

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

pub fn remove_entry(self) -> (K, V)

Takes the key-value pair out of the map, and returns it.
