Enum wgpu::PrimitiveTopology

pub enum PrimitiveTopology {
    PointList,
    LineList,
    LineStrip,
    TriangleList,
    TriangleStrip,
}

Primitive type the input mesh is composed of.

Corresponds to WebGPU GPUPrimitiveTopology.

Variants

PointList

Vertex data is a list of points. Each vertex is a new point.

LineList

Vertex data is a list of lines. Each pair of vertices composes a new line.

Vertices 0 1 2 3 create two lines 0 1 and 2 3

LineStrip

Vertex data is a strip of lines. Each set of two adjacent vertices form a line.

Vertices 0 1 2 3 create three lines 0 1, 1 2, and 2 3.

TriangleList

Vertex data is a list of triangles. Each set of 3 vertices composes a new triangle.

Vertices 0 1 2 3 4 5 create two triangles 0 1 2 and 3 4 5

TriangleStrip

Vertex data is a triangle strip. Each set of three adjacent vertices form a triangle.

Vertices 0 1 2 3 4 5 creates four triangles 0 1 2, 2 1 3, 2 3 4, and 4 3 5

Implementations

impl PrimitiveTopology

pub fn is_strip(&self) -> bool

Returns true for strip topologies.

Trait Implementations

impl Clone for PrimitiveTopology

fn clone(&self) -> PrimitiveTopology

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveTopology

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

Formats the value using the given formatter.

impl Default for PrimitiveTopology

fn default() -> PrimitiveTopology

Returns the “default value” for a type.

impl Hash for PrimitiveTopology

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<PrimitiveTopology> for PrimitiveTopology

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