Required Methods

fn Observe( &self, cx: &mut JSContext, options: &PerformanceObserverInit, ) -> Fallible<()>

fn Disconnect(&self, cx: &mut JSContext)

fn TakeRecords(&self) -> Vec<DomRoot<D::PerformanceEntry>>

fn SupportedEntryTypes( cx: &mut JSContext, global: &D::GlobalScope, retval: MutableHandle<'_, Value>, )

fn Constructor( cx: &mut JSContext, global: &D::GlobalScope, proto: Option<HandleObject<'_>>, callback: RootedCallback<PerformanceObserverCallback<D>>, ) -> Fallible<DomRoot<D::PerformanceObserver>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
