Expand description

DisplaySettings are used to determine the output state of the display. The display can be toggled between two modes, auto-brightness on and auto-brightness off.

Adjusted_auto_brightness is used to set a specific brightness level for the current lighting conditions. Auto-brightness will continue to make the screen darker and brighter as the surrounding light changes.

Brightness_value is used in manual mode to set a specific brightness level for the screen. This level will be maintained while in manual mode.

Fields§

§auto_brightness: Option<bool>

Auto brightness enabled.

§brightness_value: Option<f32>

Manually set brightness value [0.0 - 1.0]. Not a number, infinity or negative infinity will cause SetDisplayInfo to fail with INVALID_VALUE.

§low_light_mode: Option<LowLightMode>

The low light mode state of the device.

§screen_enabled: Option<bool>

Whether the screen is enabled.

§theme: Option<Theme>

Theme to be used for the device’s user interface.

§adjusted_auto_brightness: Option<f32>

Brightness value to adjust auto-brightness to [0.0 - 1.0].

impl PartialEq for DisplaySettings

source§

fn eq(&self, other: &DisplaySettings) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

impl TypeMarker for DisplaySettings

§

type Owned = DisplaySettings

The owned Rust type which this FIDL type decodes into.
source§

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.
source§

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.
§

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy. Read more
§

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
