Struct VertexDataLayout

pub struct VertexDataLayout { /* private fields */ }

Implementations

impl VertexDataLayout

pub fn new( vertex_stride: usize, vertex_rate: RafxVertexAttributeRate, members: &[VertexMember], ) -> Self

pub fn build_vertex_layout<VertexT, F: FnOnce(&mut VertexMemberAccumulator<'_, VertexT>, &VertexT)>( vertex: &VertexT, vertex_rate: RafxVertexAttributeRate, f: F, ) -> VertexDataLayout

Example usage to define a vertex data layout and convert it into a VertexDataSetLayout (VertexDataLayout::build_vertex_layout creates a VertexDataLayout and the .into_set() call makes it a single-buffer set

use rafx_api::{RafxFormat, RafxPrimitiveTopology, RafxVertexAttributeRate};

pub struct ExampleVertex {

Trait Implementations

impl Clone for VertexDataLayout

fn clone(&self) -> VertexDataLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VertexDataLayout

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

Formats the value using the given formatter.

impl PartialEq for VertexDataLayout

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