Struct WatcherProxy 

pub struct WatcherProxy { /* private fields */ }

Implementations

impl WatcherProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.net.interfaces/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<Event, DefaultFuchsiaResourceDialect>

Hanging get for an interface addition/deletion change.

Clients should only have one call of this method at a time; a second call to this method while a call is already pending will cause the server end of the protocol to be closed.

If there are N interfaces present at the time the server end of the protocol is initialized, then the first N invocations of this method will return [Event.existing] followed by a single [Event.idle] indicating that all existing interfaces have been sent. Subsequent calls will immediately return if there is a change to be reported, or block until a change occurs.

The server may choose to coalesce property change events, e.g. when multiple independent property changes occur. As a result, clients cannot assume that the order in which they observe the interface changes is the order in which the changes occurred.

• response event the interface change event.
