Implementations

impl<T: DomObjectIteratorWrap + JSTraceable + Iterable> IterableIterator<T>

pub fn new(iterable: &T, type_: IteratorType) -> Root<Dom<Self>>

Create a new iterator instance for the provided iterable DOM interface.

pub fn Next(&self, cx: JSContext) -> Result<NonNull<JSObject>, Error>

Return the next value from the iterable object.

Trait Implementations

impl<T: DomObjectIteratorWrap + JSTraceable + Iterable> DomObject for IterableIterator<T>

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<T: DomObjectIteratorWrap + JSTraceable + Iterable> DomObjectWrap for IterableIterator<T>

const WRAP: unsafe fn(_: JSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>, _: CanGc) -> Root<Dom<Self>> = T::ITER_WRAP

Function pointer to the general wrap function type

impl IDLInterface for IterableIterator<FormData>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<GPUSupportedFeatures>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<Headers>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<TestBindingMaplike>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<TestBindingPairIterable>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<TestBindingSetlike>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<URLSearchParams>

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

Returns whether the given DOM class derives that interface.

impl IDLInterface for IterableIterator<XRHand>

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

Returns whether the given DOM class derives that interface.

impl<T> MallocSizeOf for IterableIterator<T>

where T: MallocSizeOf + DomObjectIteratorWrap + JSTraceable + Iterable,

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<T: DomObjectIteratorWrap + JSTraceable + Iterable> MutDomObject for IterableIterator<T>

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

Initializes the Reflector

impl<T: DomObjectIteratorWrap + JSTraceable + Iterable> PartialEq for IterableIterator<T>

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<T: DomObjectIteratorWrap + JSTraceable + Iterable> ToJSValConvertible for IterableIterator<T>

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

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

impl<T> Traceable for IterableIterator<T>

where T: JSTraceable + DomObjectIteratorWrap + JSTraceable + Iterable,

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

Trace self.
