Implementations

impl<D: DomTypes> OnBeforeUnloadEventHandlerNonNull<D>

pub(crate) unsafe fn new( aCx: SafeJSContext, aCallback: *mut JSObject, ) -> Rc<OnBeforeUnloadEventHandlerNonNull<D>>

pub fn Call_<T: ThisReflector>( &self, thisObj: &T, event: &D::Event, aExceptionHandling: ExceptionHandling, can_gc: CanGc, ) -> Fallible<Option<DOMString>>

pub fn Call__( &self, event: &D::Event, aExceptionHandling: ExceptionHandling, can_gc: CanGc, ) -> Fallible<Option<DOMString>>

unsafe fn Call( &self, cx: SafeJSContext, aThisObj: HandleValue<'_>, event: &D::Event, can_gc: CanGc, ) -> Fallible<Option<DOMString>>

Trait Implementations

impl<D: DomTypes> CallbackContainer<D> for OnBeforeUnloadEventHandlerNonNull<D>

unsafe fn new( cx: SafeJSContext, callback: *mut JSObject, ) -> Rc<OnBeforeUnloadEventHandlerNonNull<D>>

Create a new CallbackContainer object for the given JSObject.

fn callback_holder(&self) -> &CallbackObject<D>

Returns the underlying CallbackObject.

fn callback(&self) -> *mut JSObject

Returns the underlying JSObject.

fn incumbent(&self) -> Option<&D::GlobalScope>

Returns the “callback context”, that is, the global to use as incumbent global when calling the callback.

impl<D: PartialEq + DomTypes> PartialEq for OnBeforeUnloadEventHandlerNonNull<D>

fn eq(&self, other: &OnBeforeUnloadEventHandlerNonNull<D>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<D: DomTypes> ToJSValConvertible for OnBeforeUnloadEventHandlerNonNull<D>

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl<D> Traceable for OnBeforeUnloadEventHandlerNonNull<D>

where D: JSTraceable + DomTypes,

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
