Struct dashmap::ReadOnlyView[][src]

pub struct ReadOnlyView<K, V, S = RandomState> { /* fields omitted */ }

A read-only view into a DashMap. Allows to obtain raw references to the stored values.

Implementations

impl<K, V, S> ReadOnlyView<K, V, S>[src]

pub fn into_inner(self) -> DashMap<K, V, S>[src]

Consumes this ReadOnlyView, returning the underlying DashMap.

impl<'a, K: 'a + Eq + Hash, V: 'a, S: BuildHasher + Clone> ReadOnlyView<K, V, S>[src]

pub fn len(&self) -> usize[src]

Returns the number of elements in the map.

pub fn is_empty(&self) -> bool[src]

Returns true if the map contains no elements.

pub fn capacity(&self) -> usize[src]

Returns the number of elements the map can hold without reallocating.

pub fn contains_key<Q: ?Sized>(&'a self, key: &Q) -> bool where
    K: Borrow<Q>,
    Q: Hash + Eq
[src]

Returns true if the map contains a value for the specified key.

pub fn get<Q: ?Sized>(&'a self, key: &Q) -> Option<&'a V> where
    K: Borrow<Q>,
    Q: Hash + Eq
[src]

Returns a reference to the value corresponding to the key.

pub fn get_key_value<Q: ?Sized>(&'a self, key: &Q) -> Option<(&'a K, &'a V)> where
    K: Borrow<Q>,
    Q: Hash + Eq
[src]

Returns the key-value pair corresponding to the supplied key.

pub fn iter(&'a self) -> impl Iterator<Item = (&'a K, &'a V)> + 'a[src]

An iterator visiting all key-value pairs in arbitrary order. The iterator element type is (&'a K, &'a V).

pub fn keys(&'a self) -> impl Iterator<Item = &'a K> + 'a[src]

An iterator visiting all keys in arbitrary order. The iterator element type is &'a K.

pub fn values(&'a self) -> impl Iterator<Item = &'a V> + 'a[src]

An iterator visiting all values in arbitrary order. The iterator element type is &'a V.
