Functions
template<class T>
constexpr auto	operator- (T a) -> std::enable_if_t< stlab::has_enabled_arithmetic< T >||stlab::has_enabled_bitmask< T >, T >
	Unary minus enums. For bitmask-enabled enums, this allows expressions like e & -e to return the least set bit.
template<class T>
constexpr auto	operator== (T lhs, std::nullptr_t) -> std::enable_if_t<(stlab::has_enabled_bitmask< T >||stlab::has_enabled_arithmetic< T >) &&!stlab::is_compatible_scalar< T, T >, bool >
	Equality with nullptr for bitmask or arithmetic scoped enums; true when the value is zero.
template<class T>
constexpr auto	operator== (std::nullptr_t, T rhs) -> std::enable_if_t<(stlab::has_enabled_bitmask< T >||stlab::has_enabled_arithmetic< T >) &&!stlab::is_compatible_scalar< T, T >, bool >
	Equality with nullptr for bitmask or arithmetic scoped enums; true when the value is zero.
template<class T>
constexpr auto	operator!= (T lhs, std::nullptr_t rhs) -> std::enable_if_t<(stlab::has_enabled_bitmask< T >||stlab::has_enabled_arithmetic< T >) &&!stlab::is_compatible_scalar< T, T >, bool >
	Inequality with nullptr for bitmask or arithmetic scoped enums.
template<class T>
constexpr auto	operator!= (std::nullptr_t lhs, T rhs) -> std::enable_if_t<(stlab::has_enabled_bitmask< T >||stlab::has_enabled_arithmetic< T >) &&!stlab::is_compatible_scalar< T, T >, bool >
	Inequality with nullptr for bitmask or arithmetic scoped enums.
template<class T>
constexpr auto	operator! (T lhs) -> std::enable_if_t< stlab::has_enabled_bitmask< T >||stlab::has_enabled_arithmetic< T >, bool >
	Logical NOT for bitmask or arithmetic enums; true when the value converts to false.

Detailed Description

Operations available for both bitmask and arithmetic-enabled enums.

These operations are available for enums that have either bitmask or arithmetic operations enabled.
