Expand description

Represents an allocated image buffer that can be assigned to a display layer.

Fields§

§id: ImageId

The ID of the image provided to the display driver.

§collection_id: BufferCollectionId

The ID of the sysmem buffer collection that backs this image.

§vmo: Vmo

The VMO that contains the shared image buffer.

§parameters: ImageParameters

The parameters that the image was initialized with.

§format_constraints: ImageFormatConstraints

The image format constraints that resulted from the sysmem buffer negotiation. Contains the effective image parameters.

§buffer_settings: BufferMemorySettings

The effective buffer memory settings that resulted from the sysmem buffer negotiation.

Implementations§

Source §

impl Image

Source

pub async fn create( coordinator: Coordinator, image_id: ImageId, params: &ImageParameters, ) -> Result<Image>

Construct a new sysmem-buffer-backed image and register it with the display driver using image_id. If successful, the image can be assigned to a primary layer in a display configuration.
