Struct VertexLayout 

pub struct VertexLayout { /* private fields */ }

Describes the memory layout of a single interleaved vertex record.

Attributes are stored in insertion order; the stride is computed automatically from the sum of all attribute sizes.

Implementations

impl VertexLayout

pub fn new() -> Self

Create an empty layout.

pub fn add( &mut self, name: impl Into<String>, attribute: VertexAttribute, ) -> &mut Self

Append a named attribute to the layout.

Returns &mut self for builder-style chaining.

pub fn stride(&self) -> usize

Total byte size of one vertex record (sum of all attribute sizes).

pub fn attribute_count(&self) -> usize

Number of attributes in the layout.

pub fn slots(&self) -> &[VertexSlot]

Iterate over the slots in declaration order.

pub fn slot_by_name(&self, name: &str) -> Option<&VertexSlot>

Return the slot with name, if present.

Trait Implementations

impl Clone for VertexLayout

fn clone(&self) -> VertexLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VertexLayout

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

Formats the value using the given formatter.

impl Default for VertexLayout

fn default() -> VertexLayout

Returns the “default value” for a type.
