| 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.

Parameters
| x, y | - | std::coroutine_handle<> values to compare |
Return value
1) x.address() == y.address().
2) std::compare_three_way{}(x.address(), y.address()).
Notes
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<>.
