Struct BufferDescriptor

pub struct BufferDescriptor<'a, R: Renderable + ?Sized> {
    pub data: &'a BufferData<'a, R>,
    pub stride: u32,
    pub byte_offset: u32,
    pub elements: Vec<VertexDesc>,
    /* private fields */
}

A descriptor of a subset of a BufferData, used for vertex attributes; hence for use in a vertex attribute pointer.

A BufferDescriptor is used for a single attribute of a set of data, such as Position or Normal.

Fields

data: &'a BufferData<'a, R>

The BufferData that contains the actual vertex attribute data

stride: u32

Stride of data in the buffer - 0 for count*sizeof(ele_type) Unused for indices

byte_offset: u32

Byte offset to first data inside ‘data’

elements: Vec<VertexDesc>

Description of the layout of the elements of the actual portion of buffer data

This could become a reference to a struct that is borrowed here, with its own client ref

Implementations

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

pub fn new( data: &'a BufferData<'a, R>, byte_offset: u32, stride: u32, elements: Vec<VertexDesc>, ) -> Self

Create a new view of a BufferData

pub fn create_client(&self, renderable: &mut R)

Create the render buffer required by the BufferDescriptor

pub fn borrow_client(&self) -> Ref<'_, R::Descriptor>

Borrow the client
