Public Methods
::fidl::internal::WireThenable< ::fuchsia_net_interfaces::Watcher::Watch> Watch ()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.
Allocates 16 bytes of request buffer on the stack. The callback is stored on the heap.
