Struct WatcherProxy

pub struct WatcherProxy { /* private fields */ }

Implementations

impl WatcherProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.net.filter/Watcher.

pub fn take_event_stream(&self) -> WatcherEventStream

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

Panics

Panics if the event stream was already taken.

pub fn watch( &self, ) -> QueryResponseFut<Vec<Event>, DefaultFuchsiaResourceDialect>

Hanging get for filtering resource changes.

Clients should only have one pending call of this method outstanding at a time; a second call to this method while a call is already pending will cause the server to close the channel.

The first N events returned by this method will be [Event.existing], enumerating all existing N filtering resources, followed by a single [Event.idle] indicating that all existing resources have been sent. Subsequent calls will immediately return with new events if there is at least one to be reported, or will otherwise block until an event occurs.

In order to communicate atomic updates, after the initial state is provided followed by [Event.idle], a sequence of events that occurred atomically will always be followed by [Event.end_of_update], demarcating the end of the atomic update.

Note that each non-sentinel event is scoped to a controller; the ControllerId is provided along with the event to allow the client to disambiguate.
