std::coroutine_handle<Promise>::done

Checks if a suspended coroutine is suspended at its final suspend point.

# Declarations

Member of other specializations

bool done() const;

(since C++20)

Member of specialization std::coroutine_handle<std::noop_coroutine_promise>

constexpr bool done() const noexcept;

(since C++20)

# Notes

A no-op coroutine is never considered to be suspended at its final suspend point.

A coroutine with promise object p is considered to be suspended at its final suspend point only if, let e be the result of p.final_suspend(), e.await_ready() returns false. In particular, if p.final_suspend() returns std::suspend_never, then done() never returns true.
