Class OrtMemoryAllocation

This class represents memory allocation made by a specific onnxruntime allocator. Use OrtAllocator.Allocate() to obtain an instance of this class. It implements IDisposable and makes use of the original allocator used to allocate the memory. The lifespan of the allocator instance must eclipse the lifespan of the allocation. Or, if you prefer, all OrtMemoryAllocation instances must be disposed of before the corresponding allocator instances are disposed of.
