Enum PrimitiveTopology

#[repr(C)]
pub enum PrimitiveTopology {
    PointList = 0,
    LineList = 1,
    LineStrip = 2,
    TriangleList = 3,
    TriangleStrip = 4,
}

Primitive type the input mesh is composed of.

Corresponds to WebGPU GPUPrimitiveTopology.

Variants

PointList = 0

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

LineList = 1

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 = 2

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 = 3

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 = 4

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

Vertices 0 1 2 3 4 5 create 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

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: Hasher>(&self, state: &mut __H)

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 PrimitiveTopology

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