Struct script::Reflector

pub struct Reflector {
    object: Heap<*mut JSObject>,
}

A struct to store a reference to the reflector of a DOM object.

Fields

object: Heap<*mut JSObject>

Implementations

impl Reflector

pub fn get_jsobject(&self) -> HandleObject<'_>

Get the reflector.

pub unsafe fn set_jsobject(&self, object: *mut JSObject)

Initialize the reflector. (May be called only once.)

Safety

The provided JSObject pointer must point to a valid JSObject.

pub fn rootable(&self) -> &Heap<*mut JSObject>

Return a pointer to the memory location at which the JS reflector object is stored. Used to root the reflector, as required by the JSAPI rooting APIs.

pub fn new() -> Reflector

Create an uninitialized Reflector.

Trait Implementations

impl DomObject for Reflector

fn reflector(&self) -> &Self

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 MallocSizeOf for Reflector

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 Reflector

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

Initializes the Reflector

impl PartialEq for Reflector

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

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

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

impl Traceable for Reflector

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

Trace self.
