Struct vulkano::framebuffer::EmptySinglePassRenderPass

pub struct EmptySinglePassRenderPass {
    // some fields omitted
}

Implementation of RenderPass with no attachment at all and a single pass.

When you use a EmptySinglePassRenderPass, the list of attachments and clear values must be ().

Methods

impl EmptySinglePassRenderPass

fn raw(device: &Arc<Device>) -> Result<EmptySinglePassRenderPass, RenderPassCreationError>

See the docs of new().

fn new(device: &Arc<Device>) -> Arc<EmptySinglePassRenderPass>

Builds the render pass.

Panic

• Panicks if the device or host ran out of memory.

Trait Implementations

impl RenderPass for EmptySinglePassRenderPass

fn render_pass(&self) -> &UnsafeRenderPass

Returns the underlying UnsafeRenderPass. Used by vulkano's internals.

impl RenderPassDesc for EmptySinglePassRenderPass

type AttachmentsIter = EmptyIter<LayoutAttachmentDescription>

Iterator returned by the attachments method.

type PassesIter = OptionIntoIter<LayoutPassDescription>

Iterator returned by the passes method.

type DependenciesIter = EmptyIter<LayoutPassDependencyDescription>

Iterator returned by the dependencies method.

fn attachments(&self) -> Self::AttachmentsIter

Returns an iterator that describes the list of attachments of this render pass.

fn passes(&self) -> Self::PassesIter

Returns an iterator that describes the list of passes of this render pass.

fn dependencies(&self) -> Self::DependenciesIter

Returns an iterator that describes the list of inter-pass dependencies of this render pass.

fn num_subpasses(&self) -> u32

Returns the number of subpasses within the render pass.

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

Returns the number of color attachments in 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.

impl RenderPassAttachmentsList<()> for EmptySinglePassRenderPass

type AttachmentsIter = EmptyIter<(Arc<ImageView>, Arc<Image>, ImageLayout, ImageLayout)>

A decoded A.

fn convert_attachments_list(&self, _: ()) -> Result<Self::AttachmentsIter, FramebufferCreationError>

Decodes a A into a list of attachments.

impl RenderPassClearValues<()> for EmptySinglePassRenderPass

type ClearValuesIter = EmptyIter<ClearValue>

Iterator that produces one clear value per attachment.

fn convert_clear_values(&self, _: ()) -> Self::ClearValuesIter

Decodes a C into a list of clear values where each element corresponds to an attachment. The size of the returned iterator must be the same as the number of attachments.
