Deduction guides

 

Defined in header <mdspan>
template< class... Integrals > explicit extents( Integrals... ) -> /* see below */;		(since C++23)

A deduction guide is provided for std::extents to allow deduction from integral arguments.

The deduced type is equivalent to

std::dextents<std::size_t, sizeof...(Integrals)>	(until C++26)
std::extents<std::size_t, /*maybe-static-ext*/<Integrals>...>	(since C++26)

This overload participates in overload resolution only if (std::is_convertible_v<Integrals, std::size_t> && ...) is true.
