(since C++23) | |
A deduction guide is provided for std::extents to allow deduction from integral arguments.
| 
 std::dextents<std::size_t, sizeof...(Integrals)>  | 
(until C++26) | 
| 
 std::extents<std::size_t,  | 
(since C++26) | 
This overload participates in overload resolution only if (std::is_convertible_v<Integrals, std::size_t> && ...) is true.
