Trait WeakReferenceable 

pub(crate) trait WeakReferenceable:
    Sized
    + IDLInterface
    + DomObject {
    // Provided method
    fn downgrade(&self) -> WeakRef<Self> { ... }
}

Trait implemented by weak-referenceable interfaces.

fn downgrade(&self) -> WeakRef<Self>

Downgrade a DOM object reference to a weak one.

Panics if the object is parent type not leaf type

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
