Three-way comparison operator

Synopsis

Declared in <mp-units/framework/quantity.h>

template<auto R1, typename Rep1>
  requires std::three_way_comparable<Rep1> && requires { representation_values<Rep1>::zero(); }
[[nodiscard]] constexpr auto operator<=>(quantity<R1, Rep1> const& lhs,
                                         /* implementation-defined */ rhs);

Note

This function is a hidden friend of quantity, declared inside an implementation-defined base class: it can be found only through argument-dependent lookup.

Note

The return value should not be discarded.
