Struct script::dom::dissimilaroriginwindow::DissimilarOriginWindow

#[repr(C)]
pub struct DissimilarOriginWindow {
    globalscope: GlobalScope,
    window_proxy: Dom<WindowProxy>,
    location: MutNullableDom<DissimilarOriginLocation>,
}

Represents a dissimilar-origin Window that exists in another script thread.

Since the Window is in a different script thread, we cannot access it directly, but some of its accessors (for example window.parent) still need to function.

In windowproxy.rs, we create a custom window proxy for these windows, that throws security exceptions for most accessors. This is not a replacement for XOWs, but provides belt-and-braces security.

Fields

globalscope: GlobalScope

The global for this window.

window_proxy: Dom<WindowProxy>

The window proxy for this window.

location: MutNullableDom<DissimilarOriginLocation>

The location of this window, initialized lazily.

Trait Implementations

impl Castable for DissimilarOriginWindow

fn is<T>(&self) -> boolwhere
    T: DerivedFrom<Self>,

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

impl DomObject for DissimilarOriginWindow

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 HasParent for DissimilarOriginWindow

fn as_parent(&self) -> &GlobalScope

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

type Parent = GlobalScope

impl IDLInterface for DissimilarOriginWindow

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for DissimilarOriginWindow

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 DissimilarOriginWindow

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

Initializes the Reflector

impl PartialEq<DissimilarOriginWindow> for DissimilarOriginWindow

fn eq(&self, other: &DissimilarOriginWindow) -> 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 DissimilarOriginWindow

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

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

impl Traceable for DissimilarOriginWindow

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

Trace self.
