Trait Implementations

impl XpCom for nsIPerformanceStats

const IID: nsIID

IID: nsIID = nsID(2321767755, 43606, 18027, [154, 125, 159, 145, 202, 148, 5, 239])

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 nsIPerformanceStats

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIPerformanceStats

type Target = nsIPerformanceGroupDetails

The resulting type after dereferencing.

fn deref(&self) -> &nsIPerformanceGroupDetails

Dereferences the value.
