Struct SharedSet 

pub struct SharedSet<K: Eq + Clone + Hash>(/* private fields */);

Concurrent set wrapper over DashSet providing ergonomic scoped access.

Implementations

impl<K: Eq + Hash + Clone> SharedSet<K>

pub fn new() -> Self

Create a new concurrent set.

pub fn get_cloned(&self, key: &K) -> Option<K>

Get an owned clone of an item.

This releases the set entry guard immediately, so the entry may be removed while the caller is still using the clone. Use this only when stale clones are acceptable. Prefer Self::with when later work depends on the entry still being present.

pub fn with<F, R>(&self, key: &K, f: F) -> Option<R>

where F: FnOnce(&K) -> R,

Read an item using a closure.

Caution: f runs while the entry guard is held. Avoid re-entering this SharedSet from inside the closure.

pub fn insert(&self, key: K) -> bool

Insert a key, returning true if the key was not already present.

pub fn remove(&self, key: &K) -> Option<K>

Remove a key, returning it if present.

pub fn remove_if<F>(&self, key: &K, f: F) -> Option<K>

where F: FnOnce(&K) -> bool,

Remove a key if the predicate returns true, returning it if present.

pub fn contains(&self, key: &K) -> bool

Check if a key exists.

pub fn for_each<F, Ret>(&self, f: F)

where F: FnMut(&K) -> Ret,

Iterate over all entries immutably.

Caution: f runs while an iterator entry guard is held. Avoid re-entering this SharedSet from inside the closure.

pub fn try_for_each<F, E>(&self, f: F) -> Result<(), E>

where F: FnMut(&K) -> Result<(), E>,

Fallible iteration over all entries.

Caution: f runs while an iterator entry guard is held. Avoid re-entering this SharedSet from inside the closure.

pub fn retain<F>(&self, f: F)

where F: FnMut(&K) -> bool,

Retain entries matching predicate.

Caution: f runs while DashSet is mutating internal shards. Avoid re-entering this SharedSet from inside the predicate.

pub fn items(&self) -> Vec<K>

Collect all items.

pub fn len(&self) -> usize

Number of entries.

pub fn is_empty(&self) -> bool

Check if empty.

pub fn clear(&self)

Clears the collection.

Trait Implementations

impl<K: Eq + Clone + Hash> Clone for SharedSet<K>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug + Eq + Clone + Hash> Debug for SharedSet<K>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K: Eq + Hash + Clone> Default for SharedSet<K>

fn default() -> Self

Returns the “default value” for a type.
