Classes
struct	pair< T1, T2 >
	etl::pair is a class template that provides a way to store two heterogeneous objects as a single unit. A pair is a specific case of a etl::tuple with two elements. If neither T1 nor T2 is a possibly cv-qualified class type with non-trivial destructor, or array thereof, the destructor of pair is trivial. More...

Functions
template<builtin_integer T, builtin_integer U>
constexpr auto	cmp_equal (T t, U u) noexcept -> bool
	Compare the values of two integers t and u. Unlike builtin comparison operators, negative signed integers always compare less than (and not equal to) unsigned integers: the comparison is safe against lossy integer conversion.
template<builtin_integer T, builtin_integer U>
constexpr auto	cmp_greater (T t, U u) noexcept -> bool
	Compare the values of two integers t and u. Unlike builtin comparison operators, negative signed integers always compare less than (and not equal to) unsigned integers: the comparison is safe against lossy integer conversion.
template<builtin_integer T, builtin_integer U>
constexpr auto	cmp_greater_equal (T t, U u) noexcept -> bool
	Compare the values of two integers t and u. Unlike builtin comparison operators, negative signed integers always compare less than (and not equal to) unsigned integers: the comparison is safe against lossy integer conversion.
template<builtin_integer T, builtin_integer U>
constexpr auto	cmp_less (T t, U u) noexcept -> bool
	Compare the values of two integers t and u. Unlike builtin comparison operators, negative signed integers always compare less than (and not equal to) unsigned integers: the comparison is safe against lossy integer conversion.
template<builtin_integer T, builtin_integer U>
constexpr auto	cmp_less_equal (T t, U u) noexcept -> bool
	Compare the values of two integers t and u. Unlike builtin comparison operators, negative signed integers always compare less than (and not equal to) unsigned integers: the comparison is safe against lossy integer conversion.
template<builtin_integer T, builtin_integer U>
constexpr auto	cmp_not_equal (T t, U u) noexcept -> bool
	Compare the values of two integers t and u. Unlike builtin comparison operators, negative signed integers always compare less than (and not equal to) unsigned integers: the comparison is safe against lossy integer conversion.
template<builtin_integer R, builtin_integer T>
constexpr auto	in_range (T t) noexcept -> bool
	Returns true if the value of t is in the range of values that can be represented in R, that is, if t can be converted to R without data loss.
