Struct UseSetHandle

pub struct UseSetHandle<T> { /* private fields */ }

State handle for the use_set hook.

Implementations

impl<T> UseSetHandle<T>

pub fn current(&self) -> Ref<'_, HashSet<T>>

Get immutable ref to the set.

Panics

Panics if the value is currently mutably borrowed

pub fn set(&self, set: HashSet<T>)

Set the hash set.

pub fn insert(&self, value: T) -> bool

where T: Eq + Hash,

Adds a value to the set.

pub fn replace(&self, value: T) -> Option<T>

where T: Eq + Hash,

Adds a value to the set, replacing the existing value, if any, that is equal to the given one. Returns the replaced value.

pub fn remove(&self, value: &T) -> bool

where T: Eq + Hash,

Removes a value from the set. Returns whether the value was present in the set.

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

where T: Eq + Hash, F: FnMut(&T) -> bool,

Retains only the elements specified by the predicate.

pub fn clear(&self)

Clears the set, removing all values.

Trait Implementations

impl<T> Clone for UseSetHandle<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> PartialEq for UseSetHandle<T>

where T: Eq + Hash,

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
