A (finite) map of items (node or edges) of a graph to some value.

Required methods

fn len(&self) -> usize

Return the number of items in this map.

fn clear(&mut self)

Remove all items from the map.

fn insert(&mut self, key: K, value: V) -> bool

Add one item to the map.

Return true iff u had not been contained in this map before. In this case the value is not updated.

fn insert_or_replace(&mut self, key: K, value: V) -> bool

Add one item to the map.

Return true iff key had not been contained in this map before. In this case the value is updated.

fn remove(&mut self, key: K) -> bool

Remove one item from the map.

Returns true if the item had been contained in the map, otherwise false.

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

Return a read-only reference to the element with the given key.

fn get_mut(&mut self, key: K) -> Option<&mut V>

Return a mutable reference to the element with the given key.

fn contains(&self, key: K) -> bool

Return true iff item u is contained in this map.
