Required Methods

fn get_mut<Q>(&mut self, k: &Q) -> Option<&mut Self::Element>

where Self::Key: Borrow<Q> + Hash + Eq, Q: Hash + Eq + Ord + ?Sized,

Gets the value of a key as a mutable reference.

fn insert<K, V>(&mut self, k: K, v: V) -> Option<Self::Element>

where Self::Key: From<K> + Hash + Eq, V: Into<Self::Element>,

Inserts a value

fn remove<Q>(&mut self, k: &Q) -> Option<Self::Element>

where Self::Key: Borrow<Q>, Q: Hash + Eq + Ord + ?Sized,

Removes a value from the object
