Description
This adds two new structs that allow to create watchers without having to store the full current value inline.
LazyDirectthat works likeDirectonly that it doesn't store the current value inline, only the epoch. It requiresT: Defaultand returnsT::default()when the underlying watchable has been dropped.WeakWatcherthat contains only a weak pointer to the shared state and thus is only a single pointer size long. It hasupgrade() -> Option<Direct>andlazy_upgrade() -> LazyDirectfunctions to upgrade the WeakWatcher to a watcher.With these two additions, you can use watchers for big values without increasing the size of the structs where the watcher is stored on.
