Fields

eventtarget: EventTarget

window: Dom<Window>

The associated Window for this VisualViewport,

viewport_rect: Cell<Rect<f32, CSSPixel>>

The rectangle bound of the VisualViewport, relative to the layout viewport.

scale: Cell<Scale<f32, DevicePixel, DevicePixel>>

The scale factor of VisualViewport, which is also commonly known as pinch-zoom. https://drafts.csswg.org/cssom-view/#scale-factor

Implementations

impl VisualViewport

fn __assert_parent_type(&self)

impl VisualViewport

fn new_inherited( window: &Window, viewport_rect: Rect<f32, CSSPixel>, scale: Scale<f32, DevicePixel, DevicePixel>, ) -> Self

pub(crate) fn new_from_layout_viewport( window: &Window, viewport_size: Size2D<f32, CSSPixel>, can_gc: CanGc, ) -> DomRoot<Self>

The initial visual viewport based on a layout viewport relative to the initial containing block, where the dimension would be the same as layout viewport leaving the offset and the scale to its default value.

Trait Implementations

impl Castable for VisualViewport

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 VisualViewport

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for VisualViewport

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

Function pointer to the general wrap function type

impl Drop for VisualViewport

fn drop(&mut self)

Executes the destructor for this type.

impl HasParent for VisualViewport

fn as_parent(&self) -> &EventTarget

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

type Parent = EventTarget

impl IDLInterface for VisualViewport

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for VisualViewport

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 VisualViewport

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

Initializes the Reflector

impl PartialEq for VisualViewport

fn eq(&self, other: &Self) -> 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 ToJSValConvertible for VisualViewport

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

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

impl Traceable for VisualViewport

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

Trace self.
