Enum Layout 

#[non_exhaustive]
pub enum Layout {
    Undefined,
    General,
    CopySrc,
    CopyDst,
    Sampled,
    ColorTarget,
    DepthTarget,
    DepthRead,
    Present,
}

the state a texture is in (texture_barrier, render pass attachments, write_texture)

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Undefined

contents discarded; waits for earlier colour, copy and compute work (and for the swapchain image’s acquisition)

General

storage textures and anything at once (slower on some GPUs)

CopySrc

CopyDst

Sampled

sampled in shaders (also depth textures)

ColorTarget

DepthTarget

DepthRead

depth test without writes while shaders sample it

Present

handed to the window (the last layout of a swapchain image)
