Struct Subpass

pub struct Subpass { /* private fields */ }

Represents a subpass within a RenderPass object.

This struct doesn’t correspond to anything in Vulkan. It is simply an equivalent to a tuple of a render pass and subpass index. Contrary to a tuple, however, the existence of the subpass is checked when the object is created. When you have a Subpass you are guaranteed that the given subpass does exist.

Implementations

impl Subpass

pub fn from(render_pass: Arc<RenderPass>, id: u32) -> Option<Subpass>

Returns a handle that represents a subpass of a render pass.

pub fn render_pass(&self) -> &Arc<RenderPass>

Returns the render pass of this subpass.

pub fn index(&self) -> u32

Returns the index of this subpass within the renderpass.

pub fn subpass_desc(&self) -> &SubpassDescription

Returns the subpass description for this subpass.

pub fn is_last_subpass(&self) -> bool

Returns whether this subpass is the last one in the render pass. If true is returned, calling next_subpass will panic.

pub fn next_subpass(&mut self)

Advances to the next subpass after this one.

Panics

• Panics if there are no more render passes.

pub fn num_color_attachments(&self) -> u32

Returns the number of color attachments in this subpass.

pub fn num_samples(&self) -> Option<SampleCount>

Returns the number of samples in the color and/or depth/stencil attachments. Returns None if there is no such attachment in this subpass.
