A set.

Associated Types

type Iter: Iterator<Item = &'s V>

Required Methods

fn iter(&'s self) -> Self::Iter

Returns an iterator that iterates over all items in this set.

fn insert(&'s mut self, value: V) -> Option<V>

Inserts a new value into this set, optionally returning an old value it replaces.

fn remove(&'s mut self, value: &V) -> Option<V>

Removes a value from this set, returning it.

fn contains(&'s self, value: &V) -> bool

Returns whether this set contains a value.
