Public Methods

::fidl::internal::WireThenable< ::fuchsia_ui_focus::FocusChainProvider::WatchFocusKoidChain> WatchFocusKoidChain (::fuchsia_ui_focus::wire::FocusChainProviderWatchFocusKoidChainRequest FocusChainProviderWatchFocusKoidChainRequest)

Subscribe to changes in the focus chain (koids only) with a hanging-get

pattern.

The server responds immediately with the initial state, and afterwards

whenever a change occurs. Updates are not queued up for slow clients;

only the latest state is sent.

It is invalid to call this method while a previous call is pending.

Doing so will cause the server end of the protocol to be closed.

Allocates 32 bytes of request buffer on the stack. The callback is stored on the heap.
