Struct ExampleVertices

pub struct ExampleVertices<'buffers, R: Renderable> { /* private fields */ }

This structure provides for creating example objects, particularly with regard to their vertices

It uses arrays of [Pin]ned data structures so that the data can be safely self-referential

Implementations

impl<'a, R: Renderable> ExampleVertices<'a, R>

pub fn new() -> Self

Create a new ExampleVertices

This should probably not be Pin<Box<>>

pub fn push_byte_buffer(&mut self, buffer: Box<dyn ByteBuffer>) -> usize

Push a new ByteBuffer implementation and return its index

pub fn push_index_accessor( &mut self, data: usize, num: u32, et: BufferElementType, ofs: u32, ) -> usize

Create a new [BufferAccessor] on a particular ByteBuffer instance that has already been pushed

pub fn push_data_accessor( &mut self, data: usize, num: u32, et: BufferElementType, ofs: u32, stride: u32, ) -> usize

Create a new [BufferAccessor] on a particular ByteBuffer instance that has already been pushed

pub fn push_vertices( &mut self, indices: Option<usize>, positions: usize, attrs: &[(VertexAttr, usize)], ) -> ShortIndex

Create a new Vertices using a set of indices and positions

This extends the life of the BufferAccessor to that of the ExampleVertices

This is safe as the BufferAccessor’s are in the Vec for ExampleVertices

pub fn borrow_vertices(&self, vertices: ShortIndex) -> &Vertices<'_, R>

Borrow a set of vertices; this would allow (if mut!) the vertices to have attributes added

Trait Implementations

impl<'a, R: Renderable> Default for ExampleVertices<'a, R>

fn default() -> Self

Returns the “default value” for a type.
