pub fn register_worker_scope_callback(
callback: Box<dyn FnOnce(*mut c_void, *mut c_void) + Send>,
)Expand description
Register a callback to be executed on the Worker thread the next time a
servo-native DedicatedWorkerGlobalScope::run_worker_scope finishes
constructing the Worker global object.
The callback receives (cx: *mut JSContext, global: *mut JSObject) which
are actually (*mut mozjs::jsapi::JSContext, *mut mozjs::jsapi::JSObject).
It runs on the Worker thread (not the ScriptThread).
