Struct script::dom::imagebitmap::ImageBitmap

#[repr(C)]
pub struct ImageBitmap {
    reflector_: Reflector,
    width: u32,
    height: u32,
    bitmap_data: DomRefCell<Option<Vec<u8>>>,
    origin_clean: Cell<bool>,
}

Fields

reflector_: Reflector

width: u32

height: u32

bitmap_data: DomRefCell<Option<Vec<u8>>>

The actual pixel data of the bitmap

If this is None, then the bitmap data has been released by calling close

origin_clean: Cell<bool>

Implementations

impl ImageBitmap

fn __assert_parent_type(&self)

impl ImageBitmap

fn new_inherited(width_arg: u32, height_arg: u32) -> ImageBitmap

pub fn new( global: &GlobalScope, width: u32, height: u32, ) -> Result<Root<Dom<ImageBitmap>>, Error>

Return the value of the [[Detached]] internal slot

Trait Implementations

impl DomObject for ImageBitmap

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 DomObjectWrap for ImageBitmap

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>, _: CanGc) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::ImageBitmapBinding::ImageBitmap_Binding::Wrap as for<'a, 'b> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::imagebitmap::ImageBitmap>, script_runtime::CanGc) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::imagebitmap::ImageBitmap>>}

Function pointer to the general wrap function type

impl HasParent for ImageBitmap

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 ImageBitmap

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

Returns whether the given DOM class derives that interface.

impl ImageBitmapMethods<DomTypeHolder> for ImageBitmap

fn Height(&self) -> u32

https://html.spec.whatwg.org/multipage/#dom-imagebitmap-height

fn Width(&self) -> u32

https://html.spec.whatwg.org/multipage/#dom-imagebitmap-width

fn Close(&self)

https://html.spec.whatwg.org/multipage/#dom-imagebitmap-close

impl MallocSizeOf for ImageBitmap

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 ImageBitmap

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

Initializes the Reflector

impl PartialEq for ImageBitmap

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 ImageBitmap

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

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

impl Traceable for ImageBitmap

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

Trace self.
