Trait Implementations

impl Castable for IDBCursor

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 IDBCursor

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for IDBCursor

const WRAP: unsafe fn(SafeJSContext, &GlobalScope, Option<HandleObject<'_>>, Box<Self>, CanGc) -> Root<Dom<Self>> = {script_bindings::codegen::GenericBindings::IDBCursorBinding::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::indexeddb::idbcursor::IDBCursor>, script_bindings::script_runtime::CanGc) -> script_bindings::root::Root<script_bindings::root::Dom<dom::indexeddb::idbcursor::IDBCursor>>}

Function pointer to the general wrap function type

impl HasParent for IDBCursor

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

impl IDBCursorMethods<DomTypeHolder> for IDBCursor

fn Source(&self) -> IDBObjectStoreOrIDBIndex<DomTypeHolder>

https://www.w3.org/TR/IndexedDB-2/#dom-idbcursor-source

fn Direction(&self) -> IDBCursorDirection

https://www.w3.org/TR/IndexedDB-2/#dom-idbcursor-direction

fn Key(&self, cx: SafeJSContext, can_gc: CanGc, value: MutableHandleValue<'_>)

https://www.w3.org/TR/IndexedDB-2/#dom-idbcursor-key

fn PrimaryKey( &self, cx: SafeJSContext, can_gc: CanGc, value: MutableHandleValue<'_>, )

https://www.w3.org/TR/IndexedDB-2/#dom-idbcursor-primarykey

fn Request(&self) -> DomRoot<IDBRequest>

https://w3c.github.io/IndexedDB/#dom-idbcursor-request

impl IDLInterface for IDBCursor

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for IDBCursor

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 IDBCursor

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

Initializes the Reflector

impl PartialEq for IDBCursor

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 IDBCursor

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

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

impl Traceable for IDBCursor

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

Trace self.
