LLU::TensorView Class Reference

Description

Simple, light-weight, non-owning wrappper over MTensor.

Intended for use in functions that only need to access MTensor metadata, where it can alleviate the need for introducing template parameters for MTensor passing mode (like in GenericTensor) or data type (like in Tensor class).
