Type Definition lib3h_zombie_actor::GhostCallback

type GhostCallback<UserData, CbData, E> = Box<dyn FnOnce(&mut UserData, GhostCallbackData<CbData, E>) -> GhostResult<()> + 'static>;

definition for a ghost request callback note, the callback can be registered as 'static because the code definition itself doesn't depend on any specific instance lifetime if you want to mutate the state of a struct instance, pass it in with the handle or process call. (see detach crate for help with self refs)
