Describes information about what a Surface's properties are. Fetch this with surface.compatibility(device).

Fields

image_count: RangeInclusive<SwapImageIndex>

Number of presentable images supported by the adapter for a swapchain created from this surface.

• image_count.start must be at least 1.
• image_count.end must be larger or equal to image_count.start.

current_extent: Option<Extent2D>

Current extent of the surface.

None if the surface has no explicit size, depending on the swapchain extent.

extents: RangeInclusive<Extent2D>

Range of supported extents.

current_extent must be inside this range.

max_image_layers: Layer

Maximum number of layers supported for presentable images.

Must be at least 1.

usage: Usage

Supported image usage flags.

composite_alpha: CompositeAlpha

A bitmask of supported alpha composition modes.
