Methods

impl nsIAsyncFileMetadata

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

Cast this nsIAsyncFileMetadata to one of its base interfaces.

Methods from Deref<Target = nsIFileMetadata>

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

Trait Implementations

impl XpCom for nsIAsyncFileMetadata

const IID: nsIID

IID: nsIID = nsID(3725965323, 10682, 19327, [146, 32, 163, 215, 91, 23, 174, 140])

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 nsIAsyncFileMetadata

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIAsyncFileMetadata

type Target = nsIFileMetadata

The resulting type after dereferencing.

fn deref(&self) -> &nsIFileMetadata

Dereferences the value.
