Enum vulkano::pipeline::graphics::input_assembly::PrimitiveTopology

#[non_exhaustive]
#[repr(i32)]
pub enum PrimitiveTopology {
    PointList,
    LineList,
    LineStrip,
    TriangleList,
    TriangleStrip,

    PatchList,
}

Describes how vertices must be grouped together to form primitives.

When enabling primitive restart, “list” topologies require a feature to be enabled on the device:

• The PatchList topology requires the primitive_topology_patch_list_restart feature.
• All other “list” topologies require the primitive_topology_list_restart feature.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PointList

A series of separate point primitives.

LineList

A series of separate line primitives.

LineStrip

A series of consecutive line primitives, with consecutive lines sharing a vertex.

TriangleList

A series of separate triangle primitives.

TriangleStrip

A series of consecutive triangle primitives, with consecutive triangles sharing an edge (two vertices).

TriangleFan

A series of consecutive triangle primitives, with all triangles sharing a common vertex (the first).

LineListWithAdjacency

As LineList, but with adjacency, used in combination with geometry shaders. Requires the [geometry_shader`](crate::device::Features::geometry_shader) feature.

LineStripWithAdjacency

As LineStrip, but with adjacency, used in combination with geometry shaders. Requires the geometry_shader feature.

TriangleListWithAdjacency

As TriangleList, but with adjacency, used in combination with geometry shaders. Requires the geometry_shader feature.

TriangleStripWithAdjacency

As TriangleStrip, but with adjacency, used in combination with geometry shaders. Requires the geometry_shader feature.

PatchList

Separate patch primitives, used in combination with tessellation shaders. Requires the tessellation_shader feature.

Implementations

impl PrimitiveTopology

pub fn class(&self) -> PrimitiveTopologyClass

Returns the topology class of this topology.

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 From<PrimitiveTopology> for PrimitiveTopology

fn from(val: PrimitiveTopology) -> Self

Converts to this type from the input 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,

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.

impl TryFrom<PrimitiveTopology> for PrimitiveTopology

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: PrimitiveTopology) -> Result<Self, Self::Error>

Performs the conversion.
