impl MemoryDevice<DeviceMemory> for AshMemoryDevice

unsafe fn allocate_memory(
    &self,
    size: u64,
    memory_type: u32,
    flags: AllocationFlags
) -> Result<DeviceMemory, OutOfMemory>

Allocates new memory object from device. This function may be expensive and even limit maximum number of memory objects allocated. Which is the reason for sub-allocation this crate provides.

unsafe fn deallocate_memory(&self, memory: DeviceMemory)

Deallocate memory object.

unsafe fn map_memory(
    &self,
    memory: &mut DeviceMemory,
    offset: u64,
    size: u64
) -> Result<NonNull<u8>, DeviceMapError>

Map region of device memory to host memory space.

unsafe fn unmap_memory(&self, memory: &mut DeviceMemory)

Unmap previously mapped memory region.

unsafe fn invalidate_memory_ranges(
    &self,
    ranges: &[MappedMemoryRange<'_, DeviceMemory>]
) -> Result<(), OutOfMemory>

Invalidates ranges of memory mapped regions.

unsafe fn flush_memory_ranges(
    &self,
    ranges: &[MappedMemoryRange<'_, DeviceMemory>]
) -> Result<(), OutOfMemory>

Flushes ranges of memory mapped regions.
