Provided Methods

fn is_empty(&self) -> bool

Check if the hashmap is empty.

fn len(&self) -> usize

Get the length of the hashmap.

fn capacity(&self) -> usize

Get the capacity of the hashmap.

fn get(&self, key: &K) -> Option<ReadableRef<'_, Self, V>>

where K: Hash + Eq, H: BuildHasher,

Get the value for the given key.

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

where K: Hash + Eq, H: BuildHasher,

Check if the hashmap contains the given key.
