Trait Implementations

impl XpCom for nsIMessageSender

const IID: nsIID

IID: nsIID = nsID(3143465444, 59196, 17895, [150, 81, 77, 113, 143, 75, 153, 76])

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 nsIMessageSender

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIMessageSender

type Target = nsIMessageListenerManager

The resulting type after dereferencing.

fn deref(&self) -> &nsIMessageListenerManager

Dereferences the value.
