impl Castable for Blob

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 Blob

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for Blob

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

impl Extractable for Blob

fn extract( &self, _global: &GlobalScope, can_gc: CanGc, ) -> Fallible<ExtractedBody>

impl HasParent for Blob

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 IDLInterface for Blob

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for Blob

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 Blob

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

Initializes the Reflector

impl PartialEq for Blob

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 Serializable for Blob

fn serialize(&self) -> Result<(BlobId, BlobImpl), ()>

https://w3c.github.io/FileAPI/#ref-for-serialization-steps

fn deserialize( owner: &GlobalScope, serialized: BlobImpl, can_gc: CanGc, ) -> Result<DomRoot<Self>, ()>

impl ToJSValConvertible for Blob

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

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

impl Traceable for Blob

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

Trace self.

impl WeakReferenceable for Blob

fn downgrade(&self) -> WeakRef<Self>

Downgrade a DOM object reference to a weak one.
