Describes a render (graphics) pipeline.

Fields

layout: &'a PipelineLayout

The layout of bind groups for this pipeline.

vertex_stage: ProgrammableStageDescriptor<'a>

The compiled vertex stage and its entry point.

fragment_stage: Option<ProgrammableStageDescriptor<'a>>

The compiled fragment stage and its entry point, if any.

rasterization_state: Option<RasterizationStateDescriptor>

The rasterization process for this pipeline.

primitive_topology: PrimitiveTopology

The primitive topology used to interpret vertices.

color_states: &'a [ColorStateDescriptor]

The effect of draw calls on the color aspect of the output target.

depth_stencil_state: Option<DepthStencilStateDescriptor>

The effect of draw calls on the depth and stencil aspects of the output target, if any.

vertex_state: VertexStateDescriptor<'a>

The vertex input state for this pipeline.

sample_count: u32

The number of samples calculated per pixel (for MSAA). For non-multisampled textures, this should be 1

sample_mask: u32

Bitmask that restricts the samples of a pixel modified by this pipeline. All samples can be enabled using the value !0

alpha_to_coverage_enabled: bool

When enabled, produces another sample mask per pixel based on the alpha output value, that is ANDed with the sample_mask and the primitive coverage to restrict the set of samples affected by a primitive.

The implicit mask produced for alpha of zero is guaranteed to be zero, and for alpha of one is guaranteed to be all 1-s.

Trait Implementations

impl<'a> Clone for RenderPipelineDescriptor<'a>

fn clone(&self) -> RenderPipelineDescriptor<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
