Detailed Description

Allocate raw uninitialized memory.

This class is intended to be used by host-compiler .hh code as a bridge to device memory. It allows Storage classes to allocate and manage device memory without using thrust, which requires NVCC and propagates that requirement into all downstream code.

TODO: remove the stream constructor data members and rely on Copier or thrust to do streamed async operations?
