Enum ImageLayout 

pub enum ImageLayout {
    Optimal,
    General,
    GeneralAndPresentation,
}

Defines a handful of layout options for images. Rather than a list of all possible image layouts, this reduced list is correlated with the access types to map to the correct Vulkan layouts. Optimal is usually preferred.

Variants

Optimal

Choose the most optimal layout for each usage. Performs layout transitions as appropriate for the access.

General

Layout accessible by all Vulkan access types on a device - no layout transitions except for presentation

GeneralAndPresentation

Similar to General, but also allows presentation engines to access it - no layout transitions. Requires VK_KHR_shared_presentable_image to be enabled, and this can only be used for shared presentable images (i.e. single-buffered swap chains).

Trait Implementations

impl Clone for ImageLayout

fn clone(&self) -> ImageLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ImageLayout

impl Debug for ImageLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImageLayout

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ImageLayout

fn eq(&self, other: &ImageLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
