Struct ControlProxy

pub struct ControlProxy { /* private fields */ }

Implementations

impl ControlProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.brightness/Control.

pub fn take_event_stream(&self) -> ControlEventStream

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

Panics

Panics if the event stream was already taken.

pub fn set_auto_brightness(&self) -> Result<(), Error>

Turns the auto-brightness mode on. SetManualBrightness will turn it off.

pub fn watch_auto_brightness( &self, ) -> QueryResponseFut<bool, DefaultFuchsiaResourceDialect>

Requests the current auto-brightness mode. This call implements the Hanging Get protocol.

pub fn set_manual_brightness(&self, value: f32) -> Result<(), Error>

Turns auto-brightness mode off. Used by e.g. Settings to set manual brightness using a slider Value is in the range 0.0 to 1.0 representing min to max and will be clamped if out of range.

pub fn set_manual_brightness_smooth( &self, value: f32, duration: i64, ) -> Result<(), Error>

Set manual brightness specifying the duration over which the target brightness will be set.

pub fn watch_current_brightness( &self, ) -> QueryResponseFut<f32, DefaultFuchsiaResourceDialect>

Gets the current brightness in the range 0.0 to 1.0. This result is valid for both manual and auto-brightness modes and is typically used to show the current brightness on a slider. This call implements the Hanging Get protocol.

pub fn set_auto_brightness_adjustment( &self, adjustment: f32, ) -> Result<(), Error>

Sets the brightness adjustment. This will change the brightness curve by the factor of the adjustment. The adjustment is in the range of -1.0 to 1.0.

pub fn watch_auto_brightness_adjustment( &self, ) -> QueryResponseFut<f32, DefaultFuchsiaResourceDialect>

Gets the current auto brightness adjustment. This call implements the Hanging Get protocol.

pub fn set_brightness_table(&self, table: &BrightnessTable) -> Result<(), Error>

Sets the brightness curve as a set of points. This will override the built-in brightness curve. The default brightness curve will be used if the table is empty. The connection will be closed if table errors are detected.

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

Gets the maximum supported backlight brightness in nits, if known.
