template<class IndexType, size_t... Extents, class... SliceSpecifiers> constexpr auto submdspan_canonicalize_slices(const extents<IndexType, Extents...>& src, SliceSpecifiers... slices);
1
#
Constraints: sizeof...(SliceSpecifiers) equals sizeof...(Extents).
2
#
Mandates: For each rank index k of src:
  • (2.1)
    SliceSpecifiers...[k] is a submdspan slice type for IndexType, and
  • (2.2)
    decltype(canonical-slice<IndexType>(slices...[k])) is a valid submdspan slice type for the extent of extents<IndexType, Extents...>.
3
#
Preconditions: For each rank index k of src, canonical-slice<IndexType>(slices...[k]) is a valid submdspan slice for the extent of src.
4
#
Returns: make_tuple(canonical-slice<IndexType>(slices)...).
