| 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.

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