Methods

impl nsIStreamLoaderObserver

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

Cast this nsIStreamLoaderObserver to one of its base interfaces.

impl nsIStreamLoaderObserver

pub unsafe fn OnStreamComplete(
    &self,
    loader: *const nsIStreamLoader,
    ctxt: *const nsISupports,
    status: nsresult,
    resultLength: uint32_t,
    result: *const uint8_t
) -> nsresult

/**
     * Called when the entire stream has been loaded.
     *
     * @param loader the stream loader that loaded the stream.
     * @param ctxt the context parameter of the underlying channel
     * @param status the status of the underlying channel
     * @param resultLength the length of the data loaded
     * @param result the data
     *
     * This method will always be called asynchronously by the
     * nsIStreamLoader involved, on the thread that called the
     * loader's init() method.
     *
     * If the observer wants to take over responsibility for the
     * data buffer (result), it returns NS_SUCCESS_ADOPTED_DATA
     * in place of NS_OK as its success code. The loader will then
     * "forget" about the data and not free() it after
     * onStreamComplete() returns; observer must call free()
     * when the data is no longer required.

Trait Implementations

impl XpCom for nsIStreamLoaderObserver

const IID: nsIID

IID: nsIID = nsID(899643792, 54505, 4563, [161, 165, 0, 80, 4, 28, 175, 68])

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 nsIStreamLoaderObserver

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIStreamLoaderObserver

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
