Methods

impl nsIUnicharStreamLoaderObserver

Cast this nsIUnicharStreamLoaderObserver to one of its base interfaces.

Trait Implementations

impl XpCom for nsIUnicharStreamLoaderObserver

const IID: nsIID

IID: nsIID = nsID(3264752441, 11848, 17054, [146, 183, 153, 52, 138, 22, 51, 197])

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 nsIUnicharStreamLoaderObserver

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIUnicharStreamLoaderObserver

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
