Implementations

impl OnBeforeUnloadEventHandlerNonNull

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

pub fn Call_<T: DomObject>( &self, thisObj: &T, event: &Event, aExceptionHandling: ExceptionHandling, ) -> Result<Option<DOMString>, Error>

pub fn Call__( &self, event: &Event, aExceptionHandling: ExceptionHandling, ) -> Result<Option<DOMString>, Error>

unsafe fn Call( &self, cx: SafeJSContext, aThisObj: HandleObject<'_>, event: &Event, ) -> Result<Option<DOMString>, Error>

Trait Implementations

impl CallbackContainer for OnBeforeUnloadEventHandlerNonNull

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

Create a new CallbackContainer object for the given JSObject.

fn callback_holder(&self) -> &CallbackObject

Returns the underlying CallbackObject.

fn callback(&self) -> *mut JSObject

Returns the underlying JSObject.

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

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

impl PartialEq for OnBeforeUnloadEventHandlerNonNull

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ToJSValConvertible for OnBeforeUnloadEventHandlerNonNull

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

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

impl Traceable for OnBeforeUnloadEventHandlerNonNull

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

Trace self.
