Describes how the blending system should behave for an attachment.

Fields

src_color_blend_factor: BlendFactor

The operation to apply to the source color component before applying color_op.

The default value is BlendFactor::SrcColor.

dst_color_blend_factor: BlendFactor

The operation to apply to the destination color component before applying color_op.

The default value is BlendFactor::Zero.

color_blend_op: BlendOp

The operation to apply between the color components of the source and destination pixels, to produce the final pixel value.

The default value is BlendOp::Add.

src_alpha_blend_factor: BlendFactor

The operation to apply to the source alpha component before applying alpha_op.

The default value is BlendFactor::SrcColor.

dst_alpha_blend_factor: BlendFactor

The operation to apply to the destination alpha component before applying alpha_op.

The default value is BlendFactor::Zero.

alpha_blend_op: BlendOp

The operation to apply between the alpha component of the source and destination pixels, to produce the final pixel value.

The default value is BlendOp::Add.

Implementations

impl AttachmentBlend

pub fn ignore_source() -> Self

Builds an AttachmentBlend where the output of the fragment shader is ignored and the destination is untouched.

pub fn alpha() -> Self

Builds an AttachmentBlend where the output will be merged with the existing value based on the alpha of the source.

pub fn additive() -> Self

Builds an AttachmentBlend where the colors are added, and alpha is set to the maximum of the two.

Trait Implementations

impl Clone for AttachmentBlend

fn clone(&self) -> AttachmentBlend

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttachmentBlend

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

Formats the value using the given formatter.

impl Default for AttachmentBlend

fn default() -> Self

Returns the “default value” for a type.

impl From<AttachmentBlend> for PipelineColorBlendAttachmentState

fn from(val: AttachmentBlend) -> Self

Converts to this type from the input type.

impl PartialEq for AttachmentBlend

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

This method tests for self and other values to be equal, and is used by ==.

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

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