Trait Implementations§

source§

impl<T: CustomTrace> CustomTrace for Option<T>

source§

impl<T: FromJSValConvertible> FromJSValConvertible for Option<T>

§

type Config = <T as FromJSValConvertible>::Config

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

unsafe fn from_jsval( cx: *mut JSContext, value: HandleValue<'_>, option: T::Config ) -> Result<ConversionResult<Option<T>>, ()>

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<T: ToJSValConvertible> ToJSValConvertible for Option<T>

source§

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

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

impl<T: Traceable> Traceable for Option<T>

source§

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

Trace self.
