Struct VertexBuffer 

pub struct VertexBuffer { /* private fields */ }

An in-memory buffer of interleaved vertex data with an associated layout.

Example

use oximedia_gpu::vertex_buffer::{VertexAttribute, VertexLayout, VertexBuffer};

let mut layout = VertexLayout::new();
layout.add("POSITION", VertexAttribute::Float32x3);
layout.add("TEXCOORD", VertexAttribute::Float32x2);

// 1 vertex = 20 bytes
let data = vec![0u8; 20];
let vb = VertexBuffer::new(layout, data).expect("valid vertex buffer");
assert_eq!(vb.vertex_count(), 1);
assert_eq!(vb.stride(), 20);

Implementations

impl VertexBuffer

pub fn new( layout: VertexLayout, data: Vec<u8>, ) -> Result<Self, VertexBufferError>

Create a new vertex buffer, validating that data.len() is a multiple of the layout stride.

Errors

Returns VertexBufferError::StrideMismatch if the data is not aligned to the layout stride, or VertexBufferError::Empty if the stride is zero.

pub fn stride(&self) -> usize

Byte stride between consecutive vertex records.

pub fn vertex_count(&self) -> usize

Number of complete vertex records stored in the buffer.

pub fn byte_len(&self) -> usize

Total size of the raw byte data.

pub fn as_bytes(&self) -> &[u8]

Raw byte slice for the entire buffer.

pub fn layout(&self) -> &VertexLayout

Return the layout describing this buffer’s format.

pub fn vertex_bytes(&self, index: usize) -> Option<&[u8]>

Return the raw bytes for vertex at index, or None if out of range.

Trait Implementations

impl Clone for VertexBuffer

fn clone(&self) -> VertexBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VertexBuffer

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