Struct SnackbarController 

pub struct SnackbarController<State: 'static> { /* private fields */ }

The app-state handle to a snackbar_host: a cloneable single-slot queue an app keeps in its Component::State and drives with show. Every clone shares one slot (Rc), mirroring frust::NavigatorController’s own recorded-op shape — a call here only records the request; SnackbarHostWidget drains it at its next rebuild. See the module docs for the full mount contract and the queue/replace rule this slot implements.
