Struct CoordinatorSetDisplayPowerRequest

pub struct CoordinatorSetDisplayPowerRequest {
    pub display_id: DisplayId,
    pub power_on: bool,
}

Fields

display_id: DisplayId

power_on: bool

True powers on the display, false powers it off.

Once a display is turned off, the hardware will not generate new VSync events. However, the client should be prepared to handle VSync events generated before the [Coordinator.SetDisplayPower] call reaches the hardware.

Calls that impact draft configurations, such as [Coordinator.SetDisplayLayers], still work while the display is powered off.

[Coordinator.ApplyConfig] also works while the display is powered off. When the display is powered back on on, it will show the latest applied configuration.

Newly added displays are powered on.

Trait Implementations

impl Clone for CoordinatorSetDisplayPowerRequest

fn clone(&self) -> CoordinatorSetDisplayPowerRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoordinatorSetDisplayPowerRequest

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

Formats the value using the given formatter.

impl<D> Decode<CoordinatorSetDisplayPowerRequest, D> for CoordinatorSetDisplayPowerRequest

where D: ResourceDialect,

fn new_empty() -> CoordinatorSetDisplayPowerRequest

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<D> Encode<CoordinatorSetDisplayPowerRequest, D> for &CoordinatorSetDisplayPowerRequest

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 CoordinatorSetDisplayPowerRequest

fn eq(&self, other: &CoordinatorSetDisplayPowerRequest) -> 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 CoordinatorSetDisplayPowerRequest

type Owned = CoordinatorSetDisplayPowerRequest

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 CoordinatorSetDisplayPowerRequest

type Borrowed<'a> = &'a CoordinatorSetDisplayPowerRequest

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: &<CoordinatorSetDisplayPowerRequest as TypeMarker>::Owned, ) -> <CoordinatorSetDisplayPowerRequest as ValueTypeMarker>::Borrowed<'_>

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