Trait draw2d::graphics::vulkan::device_allocator::DeviceAllocator [−][src]
pub trait DeviceAllocator {
unsafe fn allocate(
&mut self,
allocate_info: MemoryAllocateInfo
) -> Result<Allocation>;
unsafe fn free(&mut self, allocation: &Allocation) -> Result<()>;
}Expand description
The external device memory allocation interface. This is the api used by applications to allocate and free memory on the gpu.
Required methods
unsafe fn allocate(
&mut self,
allocate_info: MemoryAllocateInfo
) -> Result<Allocation>
unsafe fn allocate(
&mut self,
allocate_info: MemoryAllocateInfo
) -> Result<Allocation>
Allocate device memory with the provided type index and size.
unsafe because
- it is the responsibility of the caller to free the returned memory when it is no longer in use
- implementations do not generally check that the memory type index in allocate_info is the correct memory type index, the arguments are assumed to be correct
unsafe fn free(&mut self, allocation: &Allocation) -> Result<()>
unsafe fn free(&mut self, allocation: &Allocation) -> Result<()>
Free an allocated piece of device memory.
unsafe because
- it is the responsibility of the caller to know when the GPU is no longer using the allocation
