When I wrote > Perhaps copying a slice of an address() should be a MemoryManager operation. I was wishing for an API that *didn't always* have to allocate `unique_ptr` or `shared_ptrs` of anything to copy 4 or 8 bytes from a CPU/non-CPU Buffer to a regular CPU memory pointer. It would lower to a `memcpy` if both source and destination are CPU memory managers. A combinatorial explosion of functions to support on every `MemoryManager` is not desirable. ``` CopyBufferSliceFrom CopyBufferSliceTo CopyNonOwnedSliceFrom CopyNonOwnedSliceTo ViewBufferSliceFrom ViewBufferSliceTo ``` -- This is an automated message from the Apache Git Service.
