Struct vulkano::framebuffer::EmptySinglePassRenderPassDesc

pub struct EmptySinglePassRenderPassDesc;

Description of an empty render pass.

Can be used to create a render pass with one subpass and no attachment.

Example

use vulkano::framebuffer::EmptySinglePassRenderPassDesc;
use vulkano::framebuffer::RenderPassDesc;

let rp = EmptySinglePassRenderPassDesc.build_render_pass(device.clone());

Trait Implementations

impl RenderPassDesc for EmptySinglePassRenderPassDesc

fn num_attachments(&self) -> usize

Returns the number of attachments of the render pass.

fn attachment_desc(&self, _: usize) -> Option<AttachmentDescription>

Returns the description of an attachment.

fn num_subpasses(&self) -> usize

Returns the number of subpasses of the render pass.

fn subpass_desc(&self, num: usize) -> Option<PassDescription>

Returns the description of a subpass.

fn num_dependencies(&self) -> usize

Returns the number of dependencies of the render pass.

fn dependency_desc(&self, _: usize) -> Option<PassDependencyDescription>

Returns the description of a dependency.

fn num_color_attachments(&self, subpass: u32) -> Option<u32>

Returns the number of color attachments of a subpass. Returns None if out of range.

fn num_samples(&self, _: u32) -> Option<u32>

Returns the number of samples of the attachments of a subpass. Returns None if out of range or if the subpass has no attachment. TODO: return an enum instead?

fn has_depth_stencil_attachment(&self, subpass: u32) -> Option<(bool, bool)>

Returns a tuple whose first element is true if there's a depth attachment, and whose second element is true if there's a stencil attachment. Returns None if out of range.

fn has_depth(&self, subpass: u32) -> Option<bool>

Returns true if a subpass has a depth attachment or a depth-stencil attachment.

fn has_writable_depth(&self, subpass: u32) -> Option<bool>

Returns true if a subpass has a depth attachment or a depth-stencil attachment whose layout is not DepthStencilReadOnlyOptimal.

fn has_stencil(&self, subpass: u32) -> Option<bool>

Returns true if a subpass has a stencil attachment or a depth-stencil attachment.

fn has_writable_stencil(&self, subpass: u32) -> Option<bool>

Returns true if a subpass has a stencil attachment or a depth-stencil attachment whose layout is not DepthStencilReadOnlyOptimal.
