Available on crate feature MDLMeshBuffer only.

Used by ModelIO to represent a buffer to be filled with vertex and index data

Supports deep copy of data by conforming to the NSCopying protocol

See also Apple’s documentation

Provided Methods

unsafe fn fillData_offset(&self, data: &NSData, offset: NSUInteger)

where Self: Sized + Message,

Fills buffer with data at offset

Parameter data: Data to fill buffer with

Parameter offset: Byte offset in buffer to begin filling data

Fills data.length bytes of data. Will not write beyond length of this buffer.

unsafe fn map(&self) -> Retained<MDLMeshBufferMap>

where Self: Sized + Message,

CPU access to buffer’s memory

Returns: An MDLMeshBufferMap object to read or modify a buffer’s memory

The buffer will remain mapped as long as the returned MDLMeshBufferMap object exists. Mapping a buffer may impose restrictions on a system. For instance, if the implementing class maps an OpenGL buffer, that buffer may be unavailable for rendering while mapped, and cause a draw failure. Precautions must be taken in such cases.

unsafe fn length(&self) -> NSUInteger

where Self: Sized + Message,

Size in bytes of the buffer allocation

unsafe fn allocator( &self, ) -> Retained<ProtocolObject<dyn MDLMeshBufferAllocator>>

where Self: Sized + Message,

Allocator object used to create this buffer.

This allcoator used for copy and relayout operations (such as when a new vertex descriptor is applied to a vertex buffer)

unsafe fn zone(&self) -> Retained<ProtocolObject<dyn MDLMeshBufferZone>>

where Self: Sized + Message,

Zone from which this buffer was created

This zone will be used for copy and relayout operations (such as when a new vertex descriptor is applied to a vertex buffer). If the default zone is used this will be nil.

unsafe fn type(&self) -> MDLMeshBufferType

where Self: Sized + Message,

the intended type of the buffer
