struct	MemoryAllocation
	Represents native memory allocation coming from one of the OrtAllocators registered with OnnxRuntime. Use it to wrap an allocation made by an allocator so it can be automatically released when no longer needed. More...

struct	KernelContext
	This class wraps a raw pointer OrtKernelContext* that is being passed to the custom kernel Compute() method. Use it to safely access context attributes, input and output parameters with exception safety guarantees. See usage example in onnxruntime/test/testdata/custom_op_library/custom_op_library.cc More...

struct	KernelInfo
	This struct owns the OrtKernInfo* pointer when a copy is made. For convenient wrapping of OrtKernelInfo* passed to kernel constructor and query attributes, warp the pointer with Ort::Unowned<KernelInfo> instance so it does not destroy the pointer the kernel does not own. More...
