Public Methods

::fidl::WireResult< ::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. Response is heap-allocated.
