Implementations

impl<K: Eq, V> ShardedHashMap<K, V>

pub fn len(&self) -> usize

impl<K: Eq + Hash + Copy> ShardedHashMap<K, ()>

pub fn intern_ref<Q>(&self, value: &Q, make: impl FnOnce() -> K) -> Kwhere K: Borrow<Q>, Q: Hash + Eq + ?Sized,

pub fn intern<Q>(&self, value: Q, make: impl FnOnce(Q) -> K) -> Kwhere K: Borrow<Q>, Q: Hash + Eq,

impl<K: Eq + Hash + Copy + IntoPointer> ShardedHashMap<K, ()>

pub fn contains_pointer_to<T: Hash + IntoPointer>(&self, value: &T) -> bool

impl<T> Sharded<T>

pub fn new(value: impl FnMut() -> T) -> Self

pub fn get_shard_by_value<K: Hash + ?Sized>(&self, _val: &K) -> &Lock<T>

The shard is selected by hashing val with FxHasher.

pub fn get_shard_by_index(&self, _i: usize) -> &Lock<T>

pub fn lock_shard_by_value<K: Hash + ?Sized>( &self, _val: &K ) -> LockGuard<'_, T>

The shard is selected by hashing val with FxHasher.

pub fn lock_shard_by_hash(&self, hash: u64) -> LockGuard<'_, T>

pub fn lock_shard_by_index(&self, _i: usize) -> LockGuard<'_, T>

pub fn lock_shards(&self) -> impl Iterator<Item = LockGuard<'_, T>>

pub fn try_lock_shards(&self) -> impl Iterator<Item = Option<LockGuard<'_, T>>>

Trait Implementations

impl<T: Default> Default for Sharded<T>

fn default() -> Self

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
