Available on crate feature unstable-wgpu-29 only.

Describes the state of primitive assembly and rasterization in a render pipeline.

Corresponds to WebGPU GPUPrimitiveState.

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.

This is required for indexed drawing with strip topology and must match index buffer format, as primitive restart is always enabled in all backends and individual strips will be separated with the index value 0xFFFF when using Uint16, or 0xFFFFFFFF when using Uint32.

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.

unclipped_depth: bool

If set to true, the polygon depth is not clipped to 0-1 before rasterization.

Enabling this requires [Features::DEPTH_CLIP_CONTROL] to be enabled.

polygon_mode: PolygonMode

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

Setting this to Line requires [Features::POLYGON_MODE_LINE] to be enabled.

Setting this to Point requires [Features::POLYGON_MODE_POINT] 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 [Features::CONSERVATIVE_RASTERIZATION] to be enabled.

Trait Implementations

impl Clone for PrimitiveState

fn clone(&self) -> PrimitiveState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveState

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

Formats the value using the given formatter.

impl Default for PrimitiveState

fn default() -> PrimitiveState

Returns the “default value” for a type.

impl Hash for PrimitiveState

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

where __H: Hasher,

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 for PrimitiveState

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

Tests for self and other values to be equal, and is used by ==.

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

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