Struct DeviceProxy

pub struct DeviceProxy { /* private fields */ }

Implementations

impl DeviceProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.backlight/Device.

pub fn take_event_stream(&self) -> DeviceEventStream

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

Panics

Panics if the event stream was already taken.

pub fn get_state_normalized( &self, ) -> QueryResponseFut<DeviceGetStateNormalizedResult, DefaultFuchsiaResourceDialect>

Gets the current backlight brightness as a percentage value between 0.0 and 1.0

pub fn set_state_normalized( &self, state: &State, ) -> QueryResponseFut<DeviceSetStateNormalizedResult, DefaultFuchsiaResourceDialect>

Sets the current backlight brightness as a percentage value between 0.0 and 1.0

pub fn get_state_absolute( &self, ) -> QueryResponseFut<DeviceGetStateAbsoluteResult, DefaultFuchsiaResourceDialect>

Gets the current backlight brightness in nits

pub fn set_state_absolute( &self, state: &State, ) -> QueryResponseFut<DeviceSetStateAbsoluteResult, DefaultFuchsiaResourceDialect>

Sets the current backlight brightness in nits. Not affected by the scale set by SetNormalizedBrightnessScale.

pub fn get_max_absolute_brightness( &self, ) -> QueryResponseFut<DeviceGetMaxAbsoluteBrightnessResult, DefaultFuchsiaResourceDialect>

Gets the maximum supported backlight brightness in nits, if known. Otherwise returns error ZX_ERR_NOT_SUPPORTED.

pub fn set_normalized_brightness_scale( &self, scale: f64, ) -> QueryResponseFut<DeviceSetNormalizedBrightnessScaleResult, DefaultFuchsiaResourceDialect>

Scales the maximum normalized brightness by a percentage value in [0.0, 1.0], if supported. Otherwise returns error ZX_ERR_NOT_SUPPORTED. Values passed to SetStateNormalized will correspond to a maximum brightness of scale * GetMaxAbsoluteBrightness(). Calling this may change the current absolute brightness.

pub fn get_normalized_brightness_scale( &self, ) -> QueryResponseFut<DeviceGetNormalizedBrightnessScaleResult, DefaultFuchsiaResourceDialect>

Gets the current normalized brightness scale as a percentage value in [0.0, 1.0].

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
