Methods

impl nsIThreadRetargetableRequest

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

Cast this nsIThreadRetargetableRequest to one of its base interfaces.

impl nsIThreadRetargetableRequest

pub unsafe fn RetargetDeliveryTo(
    &self,
    aNewTarget: *const nsIEventTarget
) -> nsresult

/**
   * Called to retarget delivery of OnDataAvailable to another thread. Should
   * only be called before AsyncOpen for nsIWebsocketChannels, or during
   * OnStartRequest for nsIChannels.
   * Note: For nsIChannels, OnStartRequest and OnStopRequest will still be
   * delivered on the main thread.
   *
   * @param aNewTarget New event target, e.g. thread or threadpool.
   *
   * Note: no return value is given. If the retargeting cannot be handled,
   * normal delivery to the main thread will continue. As such, listeners
   * should be ready to deal with OnDataAvailable on either the main thread or
   * the new target thread.

   * This is only valid after OnStartRequest has been called. Any time before

Trait Implementations

impl XpCom for nsIThreadRetargetableRequest

const IID: nsIID

IID: nsIID = nsID(666389576, 23155, 19364, [168, 164, 139, 94, 100, 154, 20, 94])

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 nsIThreadRetargetableRequest

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIThreadRetargetableRequest

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
