Enum VertexAttribute 

pub enum VertexAttribute {
    Float32,
    Float32x2,
    Float32x3,
    Float32x4,
    Uint32,
    Uint32x2,
    Sint32,
    Unorm8x4,
}

The data format and dimensionality of a single vertex attribute.

Variants

Float32

Single f32 component (e.g. a scalar weight).

Float32x2

Two f32 components (e.g. UV texture coordinates).

Float32x3

Three f32 components (e.g. position XYZ or normal).

Float32x4

Four f32 components (e.g. RGBA colour or XYZW position).

Uint32

Single u32 (e.g. material index).

Uint32x2

Two u32 components.

Sint32

Single i32.

Unorm8x4

Four u8 normalised to [0, 1] (e.g. packed colours).

Implementations

impl VertexAttribute

pub const fn byte_size(self) -> usize

Size of this attribute in bytes.

pub const fn component_count(self) -> usize

Number of scalar components in this attribute.

Trait Implementations

impl Clone for VertexAttribute

fn clone(&self) -> VertexAttribute

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VertexAttribute

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for VertexAttribute

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VertexAttribute

fn eq(&self, other: &VertexAttribute) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
