Implementations§
source§impl PortWatcherProxy
impl PortWatcherProxy
sourcepub fn take_event_stream(&self) -> PortWatcherEventStream
pub fn take_event_stream(&self) -> PortWatcherEventStream
Get a Stream of events from the remote end of the PortWatcher protocol
Panics
Panics if the event stream was already taken.
sourcepub fn watch(&self) -> QueryResponseFut<DevicePortEvent>
pub fn watch(&self) -> QueryResponseFut<DevicePortEvent>
Get the next port event.
The first N calls return [DevicePortEvent.existing
] where N is the
number of ports present on the device at the time of the watcher’s
creation. The next call returns [DevicePortEvent.idle
] to indicate the
end of existing ports. Subsequent calls block until a port is added
([DevicePortEvent.added
]) or removed ([DevicePortEvent.removed
]).
The server closes the PortWatcher
channel with ZX_ERR_CANCELED
if
the number of unread events reaches a server-selected limit that is at
least two times MAX_PORTS
. Clients are encouraged to maintain a
hanging call to Watch
at all times to avoid triggering this condition.
