Struct CoordinatorSetLayerPrimaryPositionRequest

pub struct CoordinatorSetLayerPrimaryPositionRequest {
    pub layer_id: LayerId,
    pub image_source_transformation: CoordinateTransformation,
    pub image_source: RectU,
    pub display_destination: RectU,
}

Fields

layer_id: LayerId

image_source_transformation: CoordinateTransformation

Applied to the input image pixels specified by image_source.

display_destination must account for image dimensions changes caused by rotations. For example, rotating a 600x300 pixel image by 90 degrees would specify 300x600 pixel dimensions in display_destination.

image_source: RectU

The associated image region whose pixels are drawn by the layer.

The rectangle uses the Vulkan coordinate space. The origin is at the image’s top-left corner. The X axis points to the right, and the Y axis points downwards.

A valid layer definition requires a valid non-empty image source rectangle that is entirely contained within the image.

Hardware image cropping is requested implicitly, when the source region’s dimensions differ from the image’s dimensions. Some display hardware may not support cropping.

display_destination: RectU

The display image (composited output) region occupied by the layer.

The rectangle uses the Vulkan coordinate space. The origin is at the display’s top-left corner. The X axis points to the right, and the Y axis points downwards.

A valid layer definition requires a valid non-empty display destination rectangle that is entirely contained within the display.

Hardware image scaling is requested implicitly, when the output region’s dimensions differ from the dimensions of image_source. Some display hardware may not support scaling. All display hardware has limitations in scaling support.

Trait Implementations

impl Clone for CoordinatorSetLayerPrimaryPositionRequest

fn clone(&self) -> CoordinatorSetLayerPrimaryPositionRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoordinatorSetLayerPrimaryPositionRequest

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<CoordinatorSetLayerPrimaryPositionRequest, D> for CoordinatorSetLayerPrimaryPositionRequest

fn new_empty() -> Self

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<()>

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

impl<D: ResourceDialect> Encode<CoordinatorSetLayerPrimaryPositionRequest, D> for &CoordinatorSetLayerPrimaryPositionRequest

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

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

impl<D: ResourceDialect, T0: Encode<LayerId, D>, T1: Encode<CoordinateTransformation, D>, T2: Encode<RectU, D>, T3: Encode<RectU, D>> Encode<CoordinatorSetLayerPrimaryPositionRequest, D> for (T0, T1, T2, T3)

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

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

impl PartialEq for CoordinatorSetLayerPrimaryPositionRequest

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

type Owned = CoordinatorSetLayerPrimaryPositionRequest

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 CoordinatorSetLayerPrimaryPositionRequest

type Borrowed<'a> = &'a CoordinatorSetLayerPrimaryPositionRequest

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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