Fields

topology: PrimitiveTopology

The primitive topology used to interpret vertices

strip_index_format: Option<IndexFormat>

When drawing strip topologies with indices, this is the required format for the index buffer. This has no effect on non-indexed or non-strip draws.

front_face: FrontFace

The face to consider the front for the purpose of culling and stencil operations.

cull_mode: Option<Face>

The face culling mode

polygon_mode: PolygonMode

Controls the way each polygon is rasterized. Can be either Fill (default), Line or Point

Setting this to something other than Fill requires NON_FILL_POLYGON_MODE feature to be enabled

clamp_depth: bool

If set to true, the polygon depth is clamped to 0-1 range instead of being clipped.

Enabling this requires the DEPTH_CLAMPING feature to be enabled

conservative: bool

If set to true, the primitives are rendered with conservative overestimation. I.e. any rastered pixel touched by it is filled. Only valid for PolygonMode::Fill!

Enabling this requires CONSERVATIVE_RASTERIZATION features to be enabled.

count: u32

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

mask: u64

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 ANDead 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.
