Struct luminance::vertex::VertexAttribDesc

pub struct VertexAttribDesc {
    pub ty: VertexAttribType,
    pub dim: VertexAttribDim,
    pub unit_size: usize,
    pub align: usize,
}

Vertex attribute format.

Vertex attributes (such as positions, colors, texture UVs, normals, etc.) have all a specific format that must be passed to the GPU. This type gathers information about a single vertex attribute and is completly agnostic of the rest of the attributes used to form a vertex.

A type is associated with a single value of type VertexAttribDesc via the VertexAttrib trait. If such an implementor exists for a type, it means that this type can be used as a vertex attribute.

Fields

ty: VertexAttribType

Type of the attribute. See VertexAttribType for further details.

dim: VertexAttribDim

Dimension of the attribute. It should be in 1–4. See VertexAttribDim for further details.

unit_size: usize

Size in bytes that a single element of the attribute takes. That is, if your attribute has a dimension set to 2, then the unit size should be the size of a single element (not two).

align: usize

Alignment of the attribute. The best advice is to respect what Rust does, so it’s highly recommended to use ::std::mem::align_of to let it does the job for you.
