Trait Implementations

impl Castable for FileReader

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

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

fn upcast<T>(&self) -> &Twhere
    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 FileReader

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 FileReader

fn as_parent(&self) -> &EventTarget

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

type Parent = EventTarget

impl IDLInterface for FileReader

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

Returns whether the given DOM class derives that interface.

impl JSTraceable for FileReader

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

Trace self.

impl MallocSizeOf for FileReader

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 FileReader

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

Initializes the Reflector

impl PartialEq<FileReader> for FileReader

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

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

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