< cpp‎ | coroutine‎ | coroutine handle

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.

### Parameters

other | - | another `coroutine_handle` to assign from

### Return value

*this.
