Enum DrawRange 

pub enum DrawRange {
    Vertices {
        vertices: Range<u32>,
        instances: Range<u32>,
    },
    Indexed {
        indices: Range<u32>,
        base_vertex: i32,
        instances: Range<u32>,
    },
}

What to draw for one mesh.

Variants

Vertices

Draw vertices without an index buffer, instanced over instances.

Fields

vertices: Range<u32>

Vertex range to draw.

instances: Range<u32>

Instance range to draw.

Indexed

Draw indexed, instanced over instances.

Fields

indices: Range<u32>

Index range to draw.

base_vertex: i32

Value added to every index before fetching a vertex.

instances: Range<u32>

Instance range to draw.

Implementations

impl DrawRange

pub fn vertices(vertices: Range<u32>) -> Self

A single non-indexed draw of vertices.

pub fn indexed(indices: Range<u32>) -> Self

A single indexed draw of indices.

pub fn with_instances(self, instances: Range<u32>) -> Self

Draw count instances instead of one.

pub fn with_base_vertex(self, base_vertex: i32) -> Self

Offset every fetched vertex index by base_vertex (indexed draws only; a no-op for non-indexed draws).

Trait Implementations

impl Clone for DrawRange

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrawRange

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

Formats the value using the given formatter.
