[src]
pub struct Capabilities { pub min_image_count: u32, pub max_image_count: Option<u32>, pub current_extent: Option<[u32; 2]>, pub min_image_extent: [u32; 2], pub max_image_extent: [u32; 2], pub max_image_array_layers: u32, pub supported_transforms: SupportedSurfaceTransforms, pub current_transform: SurfaceTransform, pub supported_composite_alpha: SupportedCompositeAlpha, pub supported_usage_flags: ImageUsage, pub supported_formats: Vec<(Format, ColorSpace)>, pub present_modes: SupportedPresentModes, }
The capabilities of a surface when used by a physical device.
You have to match these capabilities when you create a swapchain.
Fields
min_image_count: u32
Minimum number of images that must be present in the swapchain.
max_image_count: Option<u32>
Maximum number of images that must be present in the swapchain, or None
if there is no
maximum value. Note that "no maximum" doesn't mean that you can set a very high value, as
you may still get out of memory errors.
current_extent: Option<[u32; 2]>
The current dimensions of the surface. None
means that the surface's dimensions will
depend on the dimensions of the swapchain that you are going to create.
min_image_extent: [u32; 2]
Minimum width and height of a swapchain that uses this surface.
max_image_extent: [u32; 2]
Maximum width and height of a swapchain that uses this surface.
max_image_array_layers: u32
Maximum number of image layers if you create an image array. The minimum is 1.
supported_transforms: SupportedSurfaceTransforms
List of transforms supported for the swapchain.
current_transform: SurfaceTransform
Current transform used by the surface.
supported_composite_alpha: SupportedCompositeAlpha
List of composite alpha modes supports for the swapchain.
supported_usage_flags: ImageUsage
List of image usages that are supported for images of the swapchain. Only
the color_attachment
usage is guaranteed to be supported.
supported_formats: Vec<(Format, ColorSpace)>
List of formats supported for the swapchain.
present_modes: SupportedPresentModes
List of present modes that are supported. Fifo
is always guaranteed to be supported.
