impl TryInto<&DeviceMemory<T>> for &[T]

From !70 (merged)

  • &[T] is used as a dynamic view which may be both PageLockedMemory and DeviceMemory

  • We can get where the array actually exists using Memory::memory_type()

  • Is it possible to dynamically downcast it like following?

    let mem = DeviceMemory::<i32>::zeros(ctx, 10);
let sl: &[i32] = mem.as_slice();
let mem2: DeviceMemory<i32> = sl.try_into().unwrap();

Problems

  • How to get Context?
  • How to construct a reference with avoiding double free problem?
