#[repr(C)]
pub struct IntersectionObserver { reflector_: Reflector, callback: Rc<IntersectionObserverCallback>, }
Expand description

The Intersection Observer interface

The IntersectionObserver interface can be used to observe changes in the intersection of an intersection root and one or more target Elements.

https://w3c.github.io/IntersectionObserver/#intersection-observer-interface

Fields§

§reflector_: Reflector§callback: Rc<IntersectionObserverCallback>

This callback will be invoked when there are changes to a target’s intersection with the intersection root, as per the processing model. https://w3c.github.io/IntersectionObserver/#intersection-observer-callback

Implementations§

Trait Implementations§

source§

source§

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.
source§

fn global(&self) -> Root<Dom<GlobalScope>>
where Self: Sized,

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

impl DomObjectWrap for IntersectionObserver

source§

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>, _: CanGc) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::IntersectionObserverBinding::IntersectionObserver_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::intersectionobserver::IntersectionObserver>, script_runtime::CanGc) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::intersectionobserver::IntersectionObserver>>}

Function pointer to the general wrap function type
source§

impl HasParent for IntersectionObserver

source§

fn as_parent(&self) -> &Reflector

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

§

type Parent = Reflector

source§

impl IDLInterface for IntersectionObserver

source§

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

Returns whether the given DOM class derives that interface.
source§

impl IntersectionObserverMethods<DomTypeHolder> for IntersectionObserver

source§

fn GetRoot(&self) -> Option<ElementOrDocument>

The root provided to the IntersectionObserver constructor, or null if none was provided.

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-root

source§

fn RootMargin(&self) -> DOMString

Offsets applied to the root intersection rectangle, effectively growing or shrinking the box that is used to calculate intersections. These offsets are only applied when handling same-origin-domain targets; for cross-origin-domain targets they are ignored.

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-rootmargin

source§

fn ScrollMargin(&self) -> DOMString

Offsets are applied to scrollports on the path from intersection root to target, effectively growing or shrinking the clip rects used to calculate intersections.

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-scrollmargin

source§

fn Thresholds(&self, _context: JSContext, _retval: MutableHandleValue<'_>)

A list of thresholds, sorted in increasing numeric order, where each threshold is a ratio of intersection area to bounding box area of an observed target. Notifications for a target are generated when any of the thresholds are crossed for that target. If no options.threshold was provided to the IntersectionObserver constructor, or the sequence is empty, the value of this attribute will be [0].

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-thresholds

source§

fn Delay(&self) -> i32

A number indicating the minimum delay in milliseconds between notifications from this observer for a given target.

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-delay

source§

fn TrackVisibility(&self) -> bool

A boolean indicating whether this IntersectionObserver will track changes in a target’s visibility.

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-trackvisibility

source§

fn Observe(&self, _target: &Element)

Run the observe a target Element algorithm, providing this and target.

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-observe

source§

fn Unobserve(&self, _target: &Element)

https://w3c.github.io/IntersectionObserver/#dom-intersectionobserver-unobserve

impl PartialEq for IntersectionObserver

source§

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

1.0.0 · source§

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.
source§
