Trait Implementations

impl<B> MemoryDevice<<B as Backend>::Memory> for GfxMemoryDevice<B>

where B: Backend,

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

Deallocate memory object.

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

Map region of device memory to host memory space.

unsafe fn unmap_memory(&self, memory: &mut B::Memory)

Unmap previously mapped memory region.

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

Invalidates ranges of memory mapped regions.

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

Flushes ranges of memory mapped regions.
