Trait Implementations

impl FromJSValConvertible for HTMLOrSVGImageElementOrHTMLCanvasElementOrOffscreenCanvasOrCSSStyleValue

type Config = ()

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

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

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 JSTraceable for HTMLOrSVGImageElementOrHTMLCanvasElementOrOffscreenCanvasOrCSSStyleValue

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

Trace self.

impl ToJSValConvertible for HTMLOrSVGImageElementOrHTMLCanvasElementOrOffscreenCanvasOrCSSStyleValue

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

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