Function ndarray_einsum_beta::contractors::pair_contractors::maybe_find_outputs_in_inputs_unique

fn maybe_find_outputs_in_inputs_unique(
    output_indices: &[char], 
    input_indices: &[char]
) -> Vec<Option<usize>>

Helper function used throughout this module to find the positions of one set of indices in a second set of indices. The most common case is generating a permutation to be supplied to permuted_axes.
