Struct ccthw_ash_allocator::DeviceAllocator

pub struct DeviceAllocator { /* private fields */ }

A GPU memory allocator which always allocates memory directly from the device.

Implementations

impl DeviceAllocator

pub unsafe fn new(device: Device) -> Self

Create a new device allocator.

Safety

Unsafe because:

• the device must not be destroyed while this allocater still exists
• all memory allocated by this allocator must be freed before destroying the device

Trait Implementations

impl ComposableAllocator for DeviceAllocator

unsafe fn allocate( &mut self, allocation_requirements: AllocationRequirements ) -> Result<Allocation, AllocatorError>

Allocate GPU memory based on the given requirements.

unsafe fn free(&mut self, allocation: Allocation)

Return a GPU memory allocation to the device.
