    LineStrip,

Topology of primitives.

Variants

PointList

Vertices are assembled into points. Each vertex form one point primitive.

Example

Vertirces a, b, c, d will form points a, b, c, d.

LineList

Vertices are assembled into lines. Each separate pair of vertices forms one line primitive.

Example

Vertirces a, b, c, d will form lines a, b and c, d.

LineStrip

Vertices are assembled into lines. Each pair of vertices forms one line primitive.

Example

Vertirces a, b, c, d will form lines a, b, b, c and c, d.

TriangleList

Vertices are assempled into triangles. Each separate triplet of vertices forms one triangle primitive.

Example

Vertirces a, b, c, d, e, f will form triangles a, b, c and d, e, f.

TriangleStrip

Vertices are assempled into triangles. Each triplet of vertices forms one triangle primitive.

Example

Vertirces a, b, c, d, e, f will form triangles a, b, c, b, c, d, c, d, e and d, e, f.

TriangleFan

Vertices are assempled into triangles. First vertex is shared with all triangles. Then each pair and shared vertex form one triangle primitive.

Example

Vertirces a, b, c, d, e, f will form triangles a, b, c, a, c, d, a, d, e and a, e, f.

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() -> Self

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<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.
