Trait Implementations

impl XpCom for nsIDOMBeforeUnloadEvent

const IID: nsIID

IID: nsIID = nsID(650656051, 42404, 17758, [140, 70, 105, 250, 36, 223, 169, 145])

fn query_interface<T: XpCom>(&self) -> Option<RefPtr<T>>

Perform a QueryInterface call on this object, attempting to dynamically cast it to the requested interface type. Returns Some(RefPtr) if the cast succeeded, and None otherwise.

impl RefCounted for nsIDOMBeforeUnloadEvent

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIDOMBeforeUnloadEvent

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
