coroutine_handle& operator=( std::nullptr_t ) noexcept;
(1) (since C++20)
coroutine_handle& operator=( const coroutine_handle& other ) = default;
(2) (since C++20)
coroutine_handle& operator=( coroutine_handle&& other ) = default;
(3) (since C++20)

Replaces the underlying address.

1) Replaces the underlying address with a null pointer value. After assignment, *this does not refer to a coroutine. This assignment operator is not declared for specialization std::coroutine_handle<std::noop_coroutine_promise>.
2-3) Replaces the underlying address with the one of other. Copy and move assignment operators are equivalent to implicitly declared ones.

[edit] Parameters

other - another coroutine_handle to assign from

[edit] Return value

*this.
