Struct VertexDesc

pub struct VertexDesc { /* private fields */ }

A descriptor of the contents of one aspect of data for a Vertex; in essence a ‘field’ of a Vertex structure

Such an field is a scalar, vector, or matrix of BufferElementType, starting at a byte offset within the parent structure, and it has a target VertexAttr usage

Implementations

impl VertexDesc

pub fn scalar( attr: VertexAttr, ele_type: BufferElementType, byte_offset: u16, ) -> Self

Create a scalar [VertexDescr] for a VertexAttr of a given BufferElementType, at an offset within its parent data.

pub fn vec( attr: VertexAttr, ele_type: BufferElementType, len: u8, byte_offset: u16, ) -> Self

Create a vector of ‘len’ [VertexDescr] for a VertexAttr of a given BufferElementType, at an offset within its parent data.

pub fn mat( attr: VertexAttr, ele_type: BufferElementType, dims: [u8; 2], byte_offset: u16, ) -> Self

Create a matrix of ‘dims’ [VertexDescr] for a VertexAttr of a given BufferElementType, at an offset within its parent data.

pub fn new( attr: VertexAttr, ele_type: BufferElementType, dims: [u8; 2], byte_offset: u16, ) -> Self

Create a new of ‘dims’ [VertexDescr] for a VertexAttr of a given BufferElementType, at an offset within its parent data.

pub fn vertex_attr(&self) -> VertexAttr

Retrieve the vertex attribute this field is for

pub fn byte_offset(&self) -> u16

Retrieve the byte_offset within the parent structure for this field

pub fn dims(&self) -> [u8; 2]

Retrieve the dimensions of this field - if scalar, for example, this is [0,0]

pub fn ele_type(&self) -> BufferElementType

Retrieve the BufferElementType of the field

pub fn count(&self) -> u32

Get the count of the number of elements in the field

pub fn byte_length(&self) -> u32

Get the byte length of the field
