Trait Implementations

impl BeforeUnloadEventMethods for BeforeUnloadEvent

fn ReturnValue(&self) -> DOMString

fn SetReturnValue(&self, value: DOMString)

fn IsTrusted(&self) -> bool

impl Castable for BeforeUnloadEvent

fn is<T>(&self) -> bool

where T: DerivedFrom<Self>,

Check whether a DOM object implements one of its deriving interfaces.

fn upcast<T>(&self) -> &T

where T: Castable, Self: DerivedFrom<T>,

Cast a DOM object upwards to one of the interfaces it derives from.

fn downcast<T>(&self) -> Option<&T>

where T: DerivedFrom<Self>,

Cast a DOM object downwards to one of the interfaces it might implement.

impl DomObject for BeforeUnloadEvent

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

fn global(&self) -> Root<Dom<GlobalScope>>

where Self: Sized,

Returns the global scope of the realm that the DomObject was created in.

impl DomObjectWrap for BeforeUnloadEvent

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>, _: CanGc) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::BeforeUnloadEventBinding::BeforeUnloadEvent_Binding::Wrap as for<'a, 'b> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::beforeunloadevent::BeforeUnloadEvent>, script_runtime::CanGc) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::beforeunloadevent::BeforeUnloadEvent>>}

Function pointer to the general wrap function type

impl HasParent for BeforeUnloadEvent

fn as_parent(&self) -> &Event

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = Event

impl IDLInterface for BeforeUnloadEvent

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for BeforeUnloadEvent

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl MutDomObject for BeforeUnloadEvent

unsafe fn init_reflector(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq for BeforeUnloadEvent

fn eq(&self, other: &Self) -> 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 BeforeUnloadEvent

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

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

impl Traceable for BeforeUnloadEvent

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

Trace self.
