unsafe fn TryConvertToHTMLCanvasElement( cx: SafeJSContext, value: HandleValue<'_>, ) -> Result<Option<Root<Dom<HTMLCanvasElement>>>, ()>

unsafe fn TryConvertToOffscreenCanvas( cx: SafeJSContext, value: HandleValue<'_>, ) -> Result<Option<Root<Dom<OffscreenCanvas>>>, ()>

impl HTMLCanvasElementOrOffscreenCanvas

fn size(&self) -> Size2D<u64>

Trait Implementations

impl Clone for HTMLCanvasElementOrOffscreenCanvas

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl FromJSValConvertible for HTMLCanvasElementOrOffscreenCanvas

type Config = ()

Optional configurable behaviour switch; use () for no configuration.

unsafe fn from_jsval( cx: *mut JSContext, value: HandleValue<'_>, _option: (), ) -> Result<ConversionResult<HTMLCanvasElementOrOffscreenCanvas>, ()>

Convert val to type Self. Optional configuration of type T can be passed as the option argument. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

impl MallocSizeOf for HTMLCanvasElementOrOffscreenCanvas

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 ToJSValConvertible for HTMLCanvasElementOrOffscreenCanvas

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

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

impl Traceable for HTMLCanvasElementOrOffscreenCanvas

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

Trace self.
