i need get element state and element instance's real-time data.
i attempt to use raw pointer, but it not work;
In the code above you have `element` which is the element instance, and `self` which should be the private/implementation state of it.
If you want to pass that to the closure, you could do something like
let element_clone = element.clone();
state.inspect_timer.schedule_repeating(chrono::Duration::seconds(1), move || {
let imp = YourElementType::from_instance(&element_clone); // This is the same as `self` outside the closure
[...]
})
.ignore();
Note that this keeps the element alive until the closure is dropped.
