Public Member Functions
	id_pair ()=default
	Defaulted.
	id_pair (id_pair const &)=default
	Defaulted.
id_pair &	operator= (id_pair const &)=default
	Defaulted.
	id_pair (id_pair &&)=default
	Defaulted.
id_pair &	operator= (id_pair &&)=default
	Defaulted.
	~id_pair ()=default
	Defaulted.
	id_pair (char const short_id)
	Construct an id_pair from a short ID.
	id_pair (std::string long_id)
	Construct an id_pair from a long ID.
	id_pair (char const short_id, std::string long_id)
	Construct an id_pair from a short and long ID.
bool	empty_short_id () const noexcept
	Returns true if the short ID is empty.
bool	empty_long_id () const noexcept
	Returns true if the long ID is empty.
bool	empty () const noexcept
	Returns true if both IDs are empty.
bool	has_both_ids () const noexcept
	Returns true if both IDs are non-empty.

Static Public Member Functions
template<typename id_type >
static bool	empty (id_type const &id) noexcept
	Checks whether id is empty.
template<typename id_type >
static auto	find (std::unordered_set< id_pair > const &used_ids, id_type const &id)
	Finds an id_pair in a set of used ids.
template<typename id_type >
static bool	contains (std::unordered_set< id_pair > const &used_ids, id_type const &id)
	Checks whether an id is already contained in a set of used ids.

Public Attributes
char	short_id {}
	The short identifier for the option.
std::string	long_id {}
	The long identifier for the option.

Friends
bool	operator== (id_pair const &lhs, id_pair const &rhs)
	Two id_pairs are equal if their short or long ID is equal. Empty IDs are not considered for equality. If both IDs are empty, the id_pairs are considered not equal.
bool	operator== (id_pair const &lhs, char const &rhs)
	Compares the given short ID with the short ID of the id_pair. Returns false if the id_pair's short ID is empty.
bool	operator== (id_pair const &lhs, std::string const &rhs)
	Compares the given long ID with the long ID of the id_pair. Returns false if the id_pair's long ID is empty.
