Detailed Description

template<typename R>
struct dpp::detail::task::final_awaiter< R >

The object automatically co_await-ed at the end of a task. Ensures nested coroutine chains are resolved, and the promise_t cleans up if it needs to.

Awaitable returned from task::promise_t's final_suspend. Resumes the parent and cleans up its handle if needed.

Template Parameters

R	Return type of the task

Member Function Documentation

await_ready()

template<typename R >

bool dpp::detail::task::final_awaiter< R >::await_ready ( ) const

inlinenoexcept

Always suspend at the end of the task. This allows us to clean up and resume the parent.

await_resume()

template<typename R >

void dpp::detail::task::final_awaiter< R >::await_resume ( ) const

inlinenoexcept

Function called when this object is co_awaited by the standard library at the end of final_suspend. Do nothing, return nothing.

await_suspend()

template<typename R >

std_coroutine::coroutine_handle dpp::detail::task::final_awaiter< R >::await_suspend ( handle_t< R >  handle ) const

noexcept

The suspension logic of the coroutine when it finishes. Always suspend the caller, meaning cleaning up the handle is on us.

Parameters

handle

The handle of this coroutine

Returns

std::coroutine_handle<> Handle to resume, which is either the parent if present or std::noop_coroutine() otherwise
