Associated Types
type Keys: Iterator<Item = &'m K>
type Values: Iterator<Item = &'m V>

type Iter: Iterator<Item = (&'m K, &'m V)>
type IterMut: Iterator<Item = (&'m K, &'m mut V)>
Required Methods
fn keys(&'m self) -> Self::Keys
Returns an iterator over all keys in this Map.
fn values(&'m self) -> Self::Values
Returns an iterator over all values in this Map.
fn values_mut(&'m mut self) -> Self::ValuesMut
Returns an iterator over mutable borrows to all values in this Map.
fn iter(&'m self) -> Self::Iter
Returns an iterator over all keys and their values in this Map.
fn iter_mut(&'m mut self) -> Self::IterMut
Returns an iterator over all keys and their values as mutable borrows.
fn get(&'m self, key: &K) -> Option<&'m V>
Borrows value from its key.
fn get_mut(&'m mut self, key: &K) -> Option<&'m mut V>
Borrows a value mutably from its key.
fn insert(&'m mut self, key: K, value: V) -> Option<(K, V)>
Inserts a value into this Map. If the key was already used, it
returns the old key and value pair.
fn remove(&'m mut self, key: &K) -> Option<(K, V)>
Removes a value from this Map, returning it.
Provided Methods
fn contains_key(&'m self, key: &K) -> bool
Checks whether this Map contains a value at the key.
