constexpr bool
    operator==( std::coroutine_handle<> x, std::coroutine_handle<> y ) noexcept;

(1)

(since C++20)

constexpr std::strong_ordering
    operator<=>( std::coroutine_handle<> x, std::coroutine_handle<> y ) noexcept;

(2)

(since C++20)

Compares two std::coroutine_handle<> values x and y according to their underlying addresses.

The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively.

x, y - std::coroutine_handle<> values to compare

1) x.address() == y.address()

2) std::compare_three_way{}(x.address(), y.address())

Although these operators are only overloaded for std::coroutine_handle<>, other specializations of std::coroutine_handle are also equality comparable and three-way comparable, because they are implicitly convertible to std::coroutine_handle<>.
