class TensorView#
A non-owning view of a Tensor.
This class stores a light-weight non-owning view of a Tensor. This is useful for accessing tensor data without retaining a strong reference to the Tensor. Since the caller may not always be able to pass in a strong referenced tensor.
It is the user’s responsibility to ensure that the underlying tensor data outlives the
TensorView. This responsibility extends to all data pointed to by the underlying DLTensor. This includes not only the tensor elements in data but also the memory for shape and strides.When exposing a function that expects only expects a TensorView, we recommend using ffi::TensorView as the argument type instead of ffi::Tensor.
