Struct DisplaySettings

pub struct DisplaySettings {
    pub auto_brightness: Option<bool>,
    pub brightness_value: Option<f32>,
    pub low_light_mode: Option<LowLightMode>,
    pub screen_enabled: Option<bool>,
    pub theme: Option<Theme>,
    pub adjusted_auto_brightness: Option<f32>,
    /* private fields */
}

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].

Trait Implementations

impl Clone for DisplaySettings

fn clone(&self) -> DisplaySettings

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DisplaySettings

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<D> Decode<DisplaySettings, D> for DisplaySettings

where D: ResourceDialect,

fn new_empty() -> DisplaySettings

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for DisplaySettings

fn default() -> DisplaySettings

Returns the “default value” for a type.

impl<D> Encode<DisplaySettings, D> for &DisplaySettings

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for DisplaySettings

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for DisplaySettings

type Owned = DisplaySettings

The owned Rust type which this FIDL type decodes into.

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.

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.

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.

impl ValueTypeMarker for DisplaySettings

type Borrowed<'a> = &'a DisplaySettings

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<DisplaySettings as TypeMarker>::Owned, ) -> <DisplaySettings as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
