24.7.3 Multidimensional access [views.multidim] submdspan [mdspan.submdspan] strided_slice [mdspan.submdspan.strided.slice]

strided_slice represents a set of extent regularly spaced integer indices.
The indices start at offset, and increase by increments of stride.
namespace std { template<class OffsetType, class ExtentType, class StrideType> struct strided_slice { using offset_type = OffsetType; using extent_type = ExtentType; using stride_type = StrideType; [[no_unique_address]] offset_type offset{}; [[no_unique_address]] extent_type extent{}; [[no_unique_address]] stride_type stride{}; }; }
strided_slice has the data members and special members specified above.
It has no base classes or members other than those specified.
Mandates: OffsetType, ExtentType, and StrideType are signed or unsigned integer types, or model integral-constant-like.
[Note 1: 
strided_slice{.offset = 1, .extent = 10, .stride = 3} indicates the indices 1, 4, 7, and 10.
Indices are selected from the half-open interval [1, 1 + 10).
