Public Methods
::fidl::internal::WireThenable< ::fuchsia_hardware_power_statecontrol::ShutdownWatcherRegister::RegisterWatcher> RegisterWatcher (::fidl::ClientEnd< ::fuchsia_hardware_power_statecontrol::ShutdownWatcher> && watcher)Registers a watcher to be notified when the Shutdown method is called.
Once the watcher has been successfully registered with the server, then
the request will be completed and the ShutdownWatcherRegister
channel will be left open (though a client is free to close it at this
time).
If there is an error in registering the watcher, then the
ShutdownWatcherRegister channel will be closed without completing
the request.
The provided `watcher` channel will be used at most once to notify the
watcher of an impending shutdown and allow it the chance to respond.
Watchers can unregister by closing their `ShutdownWatcher` channel.
Allocates 24 bytes of request buffer on the stack. The callback is stored on the heap.
