Public Methods
::fidl::internal::WireThenable< ::fuchsia_hardware_network::PortWatcher::Watch> Watch ()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.
- response `event` next port event.
Allocates 16 bytes of request buffer on the stack. The callback is stored on the heap.
