Expand description
A weak reference to a JS-managed DOM object.
Fields
ptr: NonNull<WeakBox<T>>
Implementations
sourceimpl<T: WeakReferenceable> WeakRef<T>
impl<T: WeakReferenceable> WeakRef<T>
sourcepub fn new(value: &T) -> Self
pub fn new(value: &T) -> Self
Create a new weak reference from a WeakReferenceable
interface instance.
This is just a convenience wrapper around <T as WeakReferenceable>::downgrade
to not have to import WeakReferenceable
.
