Methods

impl nsISupportsWeakReference

pub fn coerce<T: nsISupportsWeakReferenceCoerce>(&self) -> &T

Cast this nsISupportsWeakReference to one of its base interfaces.

    _retval: *mut *const nsIWeakReference
) -> nsresult

/**

Trait Implementations

impl XpCom for nsISupportsWeakReference

const IID: nsIID

IID: nsIID = nsID(2441657478, 63790, 4562, [129, 239, 0, 96, 8, 58, 11, 207])

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 nsISupportsWeakReference

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsISupportsWeakReference

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
