Struct MapRefMut

pub struct MapRefMut<'a, K, V> { /* private fields */ }

A mutable reference to a key-value pair in a crate::ShardMap.

Holds an exclusive lock on the shard associated with the key. Dropping this reference will release the lock.

Implementations

impl<'a, K, V> MapRefMut<'a, K, V>

where K: Eq + Hash,

pub fn key(&self) -> &K

Returns a reference to the key.

pub fn value(&self) -> &V

returns a reference to the value.

pub fn value_mut(&mut self) -> &mut V

Returns a mutable reference to the value.

pub fn pair(&self) -> (&K, &V)

Returns a reference to the key-value pair.

pub fn pair_mut(&mut self) -> (&K, &mut V)

Returns a reference to the key-value pair, with a mutable reference to the value.

Trait Implementations

impl<'a, K, V> Deref for MapRefMut<'a, K, V>

where K: Eq + Hash,

type Target = V

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, K, V> DerefMut for MapRefMut<'a, K, V>

where K: Eq + Hash,

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
