Methods

impl nsICancelable

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

Cast this nsICancelable to one of its base interfaces.

impl nsICancelable

pub unsafe fn Cancel(&self, aReason: nsresult) -> nsresult

/**
   * Call this method to request that this object abort whatever operation it
   * may be performing.
   *
   * @param aReason
   *        Pass a failure code to indicate the reason why this operation is
   *        being canceled.  It is an error to pass a success code.

Trait Implementations

impl XpCom for nsICancelable

const IID: nsIID

IID: nsIID = nsID(3645554848, 47896, 18104, [132, 78, 132, 21, 144, 100, 176, 189])

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 nsICancelable

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsICancelable

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
