Trait script::dom::promisenativehandler::Callback

pub trait Callback: JSTraceable + MallocSizeOf {
    // Required method
    fn callback(
        &self,
        cx: SafeJSContext,
        v: HandleValue<'_>,
        realm: InRealm<'_>,
        can_gc: CanGc,
    );
}

Types that implement the Callback trait follow the same rooting requirements as types that use the #[dom_struct] attribute. Prefer storing Dom<T> members inside them instead of DomRoot<T> to minimize redundant work by the garbage collector.

Required Methods

fn callback( &self, cx: SafeJSContext, v: HandleValue<'_>, realm: InRealm<'_>, can_gc: CanGc, )
