Struct DisplayPowerProxy

pub struct DisplayPowerProxy { /* private fields */ }

Implementations

impl DisplayPowerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.display.singleton/DisplayPower.

pub fn take_event_stream(&self) -> DisplayPowerEventStream

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

Panics

Panics if the event stream was already taken.

pub fn set_display_power( &self, power_on: bool, ) -> QueryResponseFut<DisplayPowerSetDisplayPowerResult, DefaultFuchsiaResourceDialect>

Set the power state of the default connected display device to power_on.

When successfull, the connected display is turned on or off. Once the display device is turned off, [fuchsia.hardware.display/Coordinator] clients will not receive OnVsync events anymore until the display device is turned on again.

Fails with ZX_ERR_NOT_SUPPORTED if the connected display fails to turn on/off.

All display devices are turned on by default.
