Struct CoordinatorListenerProxy

pub struct CoordinatorListenerProxy { /* private fields */ }

Implementations

impl CoordinatorListenerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.display/CoordinatorListener.

pub fn take_event_stream(&self) -> CoordinatorListenerEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn on_displays_changed( &self, added: &[Info], removed: &[DisplayId], ) -> Result<(), Error>

Called when displays are added or removed. Called on client creation if there are any displays already connected.

A display change always invalidates the current configuration. When a CoordinatorListener receives this method call, the corresponding Coordinator client must either apply a new configuration or revalidate and reapply their current configuration.

added and removed must not be both empty.

pub fn on_vsync( &self, display_id: &DisplayId, timestamp: i64, applied_config_stamp: &ConfigStamp, cookie: &VsyncAckCookie, ) -> Result<(), Error>

Called on every display Vertical Synchronization (Vsync) signal.

pub fn on_client_ownership_change( &self, has_ownership: bool, ) -> Result<(), Error>

Called when the corresponding Coordinator client gains or loses ownership of the displays.

A Coordinator client’s active config is displayed iff it holds the ownership of the displays.

A new Coordinator client should assume they do not have ownership of the displays until this method informs them otherwise.
