Struct vulkano::pipeline::graphics::color_blend::ColorBlendState

pub struct ColorBlendState {
    pub flags: ColorBlendStateFlags,
    pub logic_op: Option<LogicOp>,
    pub attachments: Vec<ColorBlendAttachmentState>,
    pub blend_constants: [f32; 4],
    pub _ne: NonExhaustive,
}

Describes how the color output of the fragment shader is written to the attachment. See the documentation of the blend module for more info.

Fields

flags: ColorBlendStateFlags

Additional properties of the color blend state.

The default value is empty.

logic_op: Option<LogicOp>

Sets the logical operation to perform between the incoming fragment color and the existing fragment in the framebuffer attachment.

If set to Some, the logic_op feature must be enabled on the device.

The default value is None.

attachments: Vec<ColorBlendAttachmentState>

Sets the blend and output state for each color attachment. The number of elements must match the number of color attachments in the subpass.

If there are multiple elements, and the blend and color_write_mask members of each element differ, then the independent_blend feature must be enabled on the device.

The default value is empty, which must be overridden if the subpass has color attachments.

blend_constants: [f32; 4]

The constant color to use for some of the BlendFactor variants.

The default value is [0.0; 4].

_ne: NonExhaustive

Implementations

impl ColorBlendState

pub fn with_attachment_states( count: u32, attachment_state: ColorBlendAttachmentState ) -> Self

Returns a default ColorBlendState with count duplicates of attachment_state.

pub fn new(num: u32) -> Self

👎Deprecated since 0.34.0
