Enum LoadOp 

pub enum LoadOp<T> {
    Clear(T),
    DontCare,
    Load,
}

Specifies the state of a color or combined depth and stencil attachment image during graphic render pass framebuffer load operations.

Use this to specify the desired contents of any image before use in a pipeline command buffer.

Variants

Clear(T)

Clears the attachment.

T will be ClearColorValue for color images or vk::ClearDepthStencilValue for combined depth and stencil images.

DontCare

The attachment will become undefined and reads will produce garbage data.

Load

The attachment will be preserved in memory.

Implementations

impl LoadOp<ClearColorValue>

pub const CLEAR_BLACK_ALPHA_ONE: Self

A load operation which results in a color attachment filled with rgb zeros and alpha ones.

pub const CLEAR_BLACK_ALPHA_ZERO: Self

A load operation which results in a color attachment filled with zeros.

pub const CLEAR_WHITE_ALPHA_ONE: Self

A load operation which results in a color attachment filled with rgb zeros and alpha ones.

pub const CLEAR_WHITE_ALPHA_ZERO: Self

A load operation which results in a color attachment filled with rgb ones and alpha zeros.

pub fn clear_rgba(r: f32, g: f32, b: f32, a: f32) -> Self

Convenience constructor for clear color values.

impl LoadOp<ClearDepthStencilValue>

pub const CLEAR_ONE_STENCIL_ZERO: Self

A load operation which results in a depth attachment filled with ones and stencil filled with zeros.

pub const CLEAR_ZERO_STENCIL_ZERO: Self

A load operation which results in a depth and stencil attachment filled with zeros.

pub fn clear_depth_stencil(depth: f32, stencil: u32) -> Self

Convenience constructor for clear depth and stencil values.
