Synopsis¶

Defined in header <utility>
template< auto V > (1) (since C++26)
struct nontype_t { explicit nontype_t() = default; };
template< auto V > (2) (since C++26)
inline constexpr std::nontype_t<V> nontype {};

1) The class template std::nontype_t can be used in the constructor's parameter list
to match the intended tag.
2) The corresponding std::nontype instance of (1) is a disambiguation argument tag
that can be passed to the constructors of std::function_ref to indicate that the
contained object should be constructed with the value of the non-type template
parameter V.

Template parameters¶
