Struct NavigationEventListenerProxy 

pub struct NavigationEventListenerProxy { /* private fields */ }

Implementations

impl NavigationEventListenerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.web/NavigationEventListener.

pub fn take_event_stream(&self) -> NavigationEventListenerEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn on_navigation_state_changed( &self, change: NavigationState, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Called immediately after [Frame.SetNavigationEventListener] and every time user-visible navigation state has changed. In the first call, change contains the current navigation state (empty before the first navigation request). In every following call, change will have values set for all fields that have changed at any time since the previous notification. This means that some fields may have the same value as was previously reported, for example, if they changed to some other value and back again. If a field is unset, then its value has not changed at any time since the previous notification.

Implementer must call the acknowledgement callback to receive new navigation events.
