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.

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.
