Struct BeTree

Source 
pub struct BeTree<K, V> { /* private fields */ }
Expand description

A map based on a B๐›†-tree

Implementationsยง

Sourceยง

impl<K, V> BeTree<K, V>
where K: Copy + Ord, V: Clone,

Source

pub fn new() -> Self

Create an empty B๐›†-tree.

Source

pub fn clear(&mut self)

Clear the tree, removing all entries.

Source

pub fn insert(&mut self, key: K, value: V)

Insert a key-value pair into the tree.

If the key is already present in the tree, the value is replaced. The key is not updated, though; this matters for types that can be == without being identical.

Source

pub fn delete(&mut self, key: K)

Remove a key (and its value) from the tree.

If the key is not present, silently does nothing.

Source

pub fn get(&self, key: K) -> Option<&V>

Retrieve a reference to the value corresponding to the key.
