static constexpr bool is_unique() noexcept;	(1)	(since C++23)
static constexpr bool is_exhaustive() noexcept;	(2)	(since C++23)
static constexpr bool is_strided() noexcept;	(3)	(since C++23)
static constexpr bool is_always_unique() noexcept;	(4)	(since C++23)
static constexpr bool is_always_exhaustive() noexcept;	(5)	(since C++23)
static constexpr bool is_always_strided() noexcept;	(6)	(since C++23)

Every instance of every specialization of mapping is unique, exhaustive, and strided. See LayoutMapping for the semantics of these predicate mapping traits.
