#define PUTILS_MOVE_ONLY(T) \
	T() noexcept = default; \

	T(const T &) noexcept = default; \
	T & operator=(const T &) noexcept = default;

	T(const T &) noexcept = delete; \
	T & operator=(const T &) noexcept = delete;

Deletes the copy constructor and assignment operator for T.

PUTILS_DEFAULT_MOVE

#define PUTILS_DEFAULT_MOVE(T) \
	T(T &&) noexcept = default; \
	T & operator=(T &&) noexcept = default;

Defaults the move constructor and assignment operator for T.

PUTILS_DELETE_MOVE

#define PUTILS_DELETE_MOVE(T) \
	T(T &&) noexcept = delete; \
	T & operator=(T &&) noexcept = delete;

Deletes the move constructor and assignment operator for T.

PUTILS_DELETE_COPY_AND_MOVE

#define PUTILS_DELETE_COPY_AND_MOVE(T) \
	PUTILS_DELETE_COPY(T) \
	PUTILS_DELETE_MOVE(T)

Deletes the copy and move constructors and assignment operators for T.
