Struct CommandAllocator 

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

Memory allocator for MTL4 command buffer recording.

C++ equivalent: MTL4::CommandAllocator

CommandAllocator manages memory for command buffer recording in Metal 4. It provides explicit control over memory allocation for GPU commands.

Implementations

impl CommandAllocator

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

Create a CommandAllocator from a raw pointer.

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

Get the raw pointer.

pub fn device(&self) -> Option<Device>

Get the device that created this allocator.

C++ equivalent: MTL::Device* device() const

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

Get the label.

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

pub fn allocated_size(&self) -> u64

Get the current allocated size.

C++ equivalent: uint64_t allocatedSize()

pub fn reset(&self)

Reset the allocator, freeing all allocated memory.

C++ equivalent: void reset()
