Implementations

source

impl<'a, K: Key, A: UnsafeAnyExt + ?Sized> OccupiedEntry<'a, K, A>

source

pub fn get(&self) -> &K::Value where
K::Value: Any + Implements<A>,

Get a reference to the entry’s value.

source

pub fn get_mut(&mut self) -> &mut K::Value where
K::Value: Any + Implements<A>,

Get a mutable reference to the entry’s value.

source

pub fn into_mut(self) -> &'a mut K::Value where
K::Value: Any + Implements<A>,

Transform the entry into a mutable reference with the same lifetime as the map.

source

pub fn insert(&mut self, value: K::Value) -> K::Value where
K::Value: Any + Implements<A>,

Set the entry’s value and return the previous value.

source

pub fn remove(self) -> K::Value where
K::Value: Any + Implements<A>,

Move the entry’s value out of the map, consuming the entry.
