Struct BufferDataAccessor

pub struct BufferDataAccessor<'a, R: Renderable + ?Sized> {
    pub data: &'a BufferData<'a, R>,
    pub stride: u32,
    pub elements_per_data: u32,
    pub ele_type: BufferElementType,
    pub byte_offset: u32,
    /* private fields */
}

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

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

FIXME - change to using BufferDescriptor?

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

elements_per_data: u32

For attributes: number of elements per vertex (1 to 4, or 4, 9 or 16) For indices: number of indices in the buffer

ele_type: BufferElementType

The type of each element

For indices this must be Int8, Int16 or Int32

byte_offset: u32

Offset from start of buffer to first byte of data

Implementations

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

pub fn new( data: &'a BufferData<'a, R>, count: u32, ele_type: BufferElementType, byte_offset: u32, stride: u32, ) -> Self

Create a new view of a BufferData

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

Create the render buffer required by the BufferDataAccessor

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

Borrow the client
