Struct vulkano::pipeline::vertex::BufferlessDefinition

pub struct BufferlessDefinition;

Implementation of VertexDefinition for drawing with no buffers at all.

This is only useful if your shaders come up with vertex data on their own, e.g. by inspecting gl_VertexIndex

Trait Implementations

impl<I> VertexDefinition<I> for BufferlessDefinition

type BuffersIter = Empty<(u32, usize, InputRate)>

Iterator that returns the offset, the stride (in bytes) and input rate of each buffer.

type AttribsIter = Empty<(u32, u32, AttributeInfo)>

Iterator that returns the attribute location, buffer id, and infos.

fn definition(
    &self,
    _: &I
) -> Result<(Self::BuffersIter, Self::AttribsIter), IncompatibleVertexDefinitionError>

Builds the vertex definition to use to link this definition to a vertex shader's input interface.

impl VertexSource<BufferlessVertices> for BufferlessDefinition

fn decode(
    &self,
    n: BufferlessVertices
) -> (Vec<Box<dyn BufferAccess + Sync + Send + 'static>>, usize, usize)

Checks and returns the list of buffers with offsets, number of vertices and number of instances.

impl<T> VertexSource<Vec<T>> for BufferlessDefinition

fn decode<'l>(
    &self,
    _: Vec<T>
) -> (Vec<Box<dyn BufferAccess + Sync + Send + 'static>>, usize, usize)

Checks and returns the list of buffers with offsets, number of vertices and number of instances.
