impl<'a, K: Hash + Eq, V, S: BuildHasher> Group<'a, K, V, S>[src]
pub fn builder() -> GroupBuilder<'a, K, V, S>[src]
Returns a builder for a group.
pub fn capacity(&self) -> usize[src]
Returns the capacity of the group.
pub fn len(&self) -> usize[src]
Returns the number of items in the group.
pub fn is_empty(&self) -> bool[src]
Returns true if the group is empty.
pub fn insert(&mut self, k: K, v: V) -> Option<V>[src]
Inserts an item into the group.
pub fn remove(&mut self, k: &K) -> Option<V>[src]
