.all_close()- use approx feature and methods like.abs_diff_eqinstead.scalar_sum()as deprecated - use.sum()insteadDataClone- useData + RawDataCloneinsteadArrayView::into_slice- useto_slice()instead.Fixes #863
ArrayView::into_slicevsto_sliceLooking closely at this one, I'd want to use the name
into_slice.The "into" semantic is for preserving the lifetime from the input
to the output - and for setting it more apart from the general
ArrayBase::as_slice.However, both names
into-sliceandto-slicehave pros and consand in the interest of reducing churn, the already deprecated method
loses in the tiebreaker IMO, and so
into_sliceis removed becauseclippy said so.
