Struct screen_13::driver::graphic::BlendMode

pub struct BlendMode {
    pub blend_enable: bool,
    pub src_color_blend_factor: BlendFactor,
    pub dst_color_blend_factor: BlendFactor,
    pub color_blend_op: BlendOp,
    pub src_alpha_blend_factor: BlendFactor,
    pub dst_alpha_blend_factor: BlendFactor,
    pub alpha_blend_op: BlendOp,
    pub color_write_mask: ColorComponentFlags,
}

Specifies color blend state used when rasterization is enabled for any color attachments accessed during rendering.

See VkPipelineColorBlendAttachmentState.

Fields

blend_enable: bool

Controls whether blending is enabled for the corresponding color attachment.

If blending is not enabled, the source fragment’s color for that attachment is passed through unmodified.

src_color_blend_factor: BlendFactor

Selects which blend factor is used to determine the source factors.

dst_color_blend_factor: BlendFactor

Selects which blend factor is used to determine the destination factors.

color_blend_op: BlendOp

Selects which blend operation is used to calculate the RGB values to write to the color attachment.

src_alpha_blend_factor: BlendFactor

Selects which blend factor is used to determine the source factor.

dst_alpha_blend_factor: BlendFactor

Selects which blend factor is used to determine the destination factor.

alpha_blend_op: BlendOp

Selects which blend operation is used to calculate the alpha values to write to the color attachment.

color_write_mask: ColorComponentFlags

A bitmask of specifying which of the R, G, B, and/or A components are enabled for writing, as described for the Color Write Mask.

Implementations

impl BlendMode

pub const REPLACE: Self = _

A commonly used blend mode for replacing color attachment values with new ones.

pub const ALPHA: Self = _

A commonly used blend mode for blending color attachment values based on the alpha channel.

pub const PRE_MULTIPLIED_ALPHA: Self = _

A commonly used blend mode for blending color attachment values based on the alpha channel, where the color components have been pre-multiplied with the alpha component value.

pub fn new() -> BlendModeBuilder

Specifies a default blend mode which is not enabled.

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlendMode

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

Formats the value using the given formatter.

impl Default for BlendMode

fn default() -> Self

Returns the “default value” for a type.

impl Hash for BlendMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<BlendMode> for BlendMode

fn eq(&self, other: &BlendMode) -> 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.
