Methods

impl nsIUUIDGenerator

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

Cast this nsIUUIDGenerator to one of its base interfaces.

   * Obtains a new UUID using appropriate platform-specific methods to
   * obtain a nsID that can be considered to be globally unique.

Trait Implementations

impl XpCom for nsIUUIDGenerator

const IID: nsIID

IID: nsIID = nsID(327864754, 50836, 16844, [178, 1, 51, 60, 233, 54, 216, 184])

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 nsIUUIDGenerator

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIUUIDGenerator

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
