Enum sierra::Layout

pub enum Layout {
    General,
    ColorAttachmentOptimal,

}

Image layout defines how texel are placed in memory. Operations can be used in one or more layouts. User is responsible to insert layout transition commands to ensure that the image is in valid layout for each operation. Pipeline barriers can be used to change layouts. Additionally render pass can change layout of its attachments.

Variants

General

Can be used with all device operations. Only presentation is not possible in this layout. Operations may perform slower in this layout.

ColorAttachmentOptimal

Can be used for color attachments.

DepthStencilAttachmentOptimal

Can be used for depth-stencil attachments.

DepthStencilReadOnlyOptimal

Can be used for depth-stencil attachments without writes.

ShaderReadOnlyOptimal

Can be used for images accessed from shaders without writes.

TransferSrcOptimal

Can be used for copy, blit and other transferring operations on source image.

TransferDstOptimal

Can be used for copy, blit and other transferring operations on destination image.

Present

Layout for swapchain images presentation. Should not be used if presentation feature is not enabled.
