Struct horde::sync_table::Read

pub struct Read<'a, K, V, S = DefaultHashBuilder> { /* fields omitted */ }

A handle to a SyncTable with read access.

It is acquired either by a pin, or by exclusive access to the table.

Implementations

impl<'a, K, V, S: BuildHasher> Read<'a, K, V, S>

pub fn get_potential<Q: ?Sized>(
    self,
    key: &Q,
    hash: Option<u64>
) -> Result<(&'a K, &'a V), PotentialSlot<'a>> where
    K: Borrow<Q>,
    Q: Eq + Hash, 

Gets a reference to an element in the table or a potential location where that element could be.

pub fn get<Q: ?Sized>(
    self,
    key: &Q,
    hash: Option<u64>
) -> Option<(&'a K, &'a V)> where
    K: Borrow<Q>,
    Q: Eq + Hash, 

Gets a reference to an element in the table.

impl<'a, K, V, S> Read<'a, K, V, S>

pub fn get_with_eq(
    self,
    hash: u64,
    eq: impl FnMut(&K, &V) -> bool
) -> Option<(&'a K, &'a V)>

Gets a reference to an element in the table with a custom equality function.

pub fn capacity(self) -> usize

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

pub fn len(self) -> usize

Returns the number of elements in the table.

pub fn iter(self) -> Iter<'a, K, V>

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

Trait Implementations

impl<K, V, S> Clone for Read<'_, K, V, S>

fn clone(&self) -> Self

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
