[edit]

Defined in header`<expected>`
struct unexpect_t{explicit unexpect_t()=default;};	(1)	(since C++23)
inlineconstexpr std::unexpect_t unexpect{};	(2)	(since C++23)

1) A tag type for in-place construction of an unexpected value in anstd::expected object.

2) A constant of typeconst std::unexpect_t which is usually directly passed to a constructor ofstd::expected to construct an unexpected value.

[edit]Notes

Like other construction tag types,unexpect_t is a trivial, empty class with an explicit default constructor.
