Methods

impl nsIThreadRetargetableStreamListener

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

Cast this nsIThreadRetargetableStreamListener to one of its base interfaces.

impl nsIThreadRetargetableStreamListener

pub unsafe fn CheckListenerChain(&self) -> nsresult

/**
   * Checks this listener and any next listeners it may have to verify that
   * they can receive OnDataAvailable off the main thread. It is the
   * responsibility of the implementing class to decide on the criteria to
   * determine if retargeted delivery of these methods is possible, but it must
   * check any and all nsIStreamListener objects that might be called in the
   * listener chain.
   *
   * An exception should be thrown if a listener in the chain does not
   * support retargeted delivery, i.e. if the next listener does not implement
   * nsIThreadRetargetableStreamListener, or a call to its checkListenerChain()
   * fails.

Methods from Deref<Target = nsISupports>

Trait Implementations

impl XpCom for nsIThreadRetargetableStreamListener

const IID: nsIID

IID: nsIID = nsID(4213376184, 63535, 17459, [175, 104, 216, 116, 162, 235, 189, 193])

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 nsIThreadRetargetableStreamListener

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIThreadRetargetableStreamListener

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
