Function numpy::einsum_bound

pub fn einsum_bound<'py, T, OUT>(
    subscripts: &str,
    arrays: &[Borrowed<'_, 'py, PyArray<T, IxDyn>>]
) -> PyResult<OUT>
where
    T: Element,
    OUT: ArrayOrScalar<'py, T>,

Return the Einstein summation convention of given tensors.

This is usually invoked via the the einsum! macro.
