Expand description

let new_view = obj.view_singleton(tensor_view);

This trait represents contractions that can be performed by returning a view of the original tensor. The structs that currently implement this view are the ones that don’t perform any summation over indices and hence return only a subset of the elements of the original tensor: Identity, Permutation, and Diagonalization. Note that whether Diagonalization can actually return a view is dependent on the memory layout of the input tensor; if the input tensor is not contiguous, diag.view_singleton() will panic.
