Struct DeviceSynchronousProxy

pub struct DeviceSynchronousProxy { /* private fields */ }

Implementations

impl DeviceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DeviceEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn get_state_normalized( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceGetStateNormalizedResult, Error>

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

pub fn set_state_normalized( &self, state: &State, ___deadline: MonotonicInstant, ) -> Result<DeviceSetStateNormalizedResult, Error>

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

pub fn get_state_absolute( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceGetStateAbsoluteResult, Error>

Gets the current backlight brightness in nits

pub fn set_state_absolute( &self, state: &State, ___deadline: MonotonicInstant, ) -> Result<DeviceSetStateAbsoluteResult, Error>

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

pub fn get_max_absolute_brightness( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceGetMaxAbsoluteBrightnessResult, Error>

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, ___deadline: MonotonicInstant, ) -> Result<DeviceSetNormalizedBrightnessScaleResult, Error>

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, ___deadline: MonotonicInstant, ) -> Result<DeviceGetNormalizedBrightnessScaleResult, Error>

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