Struct script::dom::bindings::weakref::WeakRefEntry

pub struct WeakRefEntry<'a, T: WeakReferenceable> {
    vec: &'a mut WeakRefVec<T>,
    index: &'a mut usize,
}

An entry of a vector of weak references. Passed to the closure given to WeakRefVec::update.

Fields

vec: &'a mut WeakRefVec<T>

index: &'a mut usize

Implementations

impl<'a, T: WeakReferenceable + 'a> WeakRefEntry<'a, T>

pub fn remove(self) -> WeakRef<T>

Remove the entry from the underlying vector of weak references.

Methods from Deref<Target = WeakRef<T>>

pub fn root(&self) -> Option<Root<Dom<T>>>

DomRoot a weak reference. Returns None if the object was already collected.

pub fn is_alive(&self) -> bool

Return whether the weakly-referenced object is still alive.

Trait Implementations

impl<'a, T: WeakReferenceable + 'a> Deref for WeakRefEntry<'a, T>

type Target = WeakRef<T>

The resulting type after dereferencing.

fn deref(&self) -> &WeakRef<T>

Dereferences the value.

impl<'a, T: WeakReferenceable + 'a> Drop for WeakRefEntry<'a, T>

fn drop(&mut self)

Executes the destructor for this type.
