Struct VertexAttribute 

pub struct VertexAttribute(/* private fields */);

Vertex attribute reflection information.

C++ equivalent: MTL::VertexAttribute

Contains information about a vertex attribute in a vertex function.

Implementations

impl VertexAttribute

pub fn alloc() -> Option<Self>

Allocate a new vertex attribute.

C++ equivalent: static VertexAttribute* alloc()

pub fn init(&self) -> Option<Self>

Initialize an allocated vertex attribute.

C++ equivalent: VertexAttribute* init()

pub fn new() -> Option<Self>

Create a new vertex attribute.

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Create from a raw pointer.

Safety

The pointer must be a valid Metal vertex attribute object.

pub fn as_raw(&self) -> *mut c_void

Get the raw pointer.

pub fn name(&self) -> Option<String>

Get the attribute name.

C++ equivalent: NS::String* name() const

pub fn attribute_index(&self) -> UInteger

Get the attribute index.

C++ equivalent: NS::UInteger attributeIndex() const

pub fn attribute_type(&self) -> DataType

Get the attribute data type.

C++ equivalent: DataType attributeType() const

pub fn is_active(&self) -> bool

Check if the attribute is active.

C++ equivalent: bool isActive() const

pub fn is_patch_data(&self) -> bool

Check if this is patch data.

C++ equivalent: bool isPatchData() const

pub fn is_patch_control_point_data(&self) -> bool

Check if this is patch control point data.

C++ equivalent: bool isPatchControlPointData() const
