Struct vulkano::framebuffer::LayoutPassDescription

pub struct LayoutPassDescription {
    pub color_attachments: Vec<(usize, ImageLayout)>,
    pub depth_stencil: Option<(usize, ImageLayout)>,
    pub input_attachments: Vec<(usize, ImageLayout)>,
    pub resolve_attachments: Vec<(usize, ImageLayout)>,
    pub preserve_attachments: Vec<usize>,
}

Describes one of the passes of a render pass.

Restrictions

All these restrictions are checked when the UnsafeRenderPass object is created. TODO: that's not the case ^

• The number of color attachments must be less than the limit of the physical device.
• All the attachments in color_attachments and depth_stencil must have the same samples count.
• If any attachment is used as both an input attachment and a color or depth/stencil attachment, then each use must use the same layout.
• Elements of preserve_attachments must not be used in any of the other members.
• If resolve_attachments is not empty, then all the resolve attachments must be attachments with 1 sample and all the color attachments must have more than 1 sample.
• If resolve_attachments is not empty, all the resolve attachments must have the same format as the color attachments.
• If the first use of an attachment in this renderpass is as an input attachment and the attachment is not also used as a color or depth/stencil attachment in the same subpass, then the loading operation must not be Clear.

Fields

color_attachments: Vec<(usize, ImageLayout)>

Indices and layouts of attachments to use as color attachments.

depth_stencil: Option<(usize, ImageLayout)>

Index and layout of the attachment to use as depth-stencil attachment.

input_attachments: Vec<(usize, ImageLayout)>

Indices and layouts of attachments to use as input attachments.

resolve_attachments: Vec<(usize, ImageLayout)>

If not empty, each color attachment will be resolved into each corresponding entry of this list.

If this value is not empty, it must be the same length as color_attachments.

preserve_attachments: Vec<usize>

Indices of attachments that will be preserved during this pass.
