final_suspend()

template<typename R >

final_awaiter<R> dpp::detail::task::promise_t< R >::final_suspend ( ) const

inlinenoexcept

Function called by the standard library when the coroutine reaches its last suspension point.

Returns

final_awaiter Special object containing the chain resolution and clean-up logic.

get_return_object()

template<typename R >

dpp::task<R> dpp::detail::task::promise_t< R >::get_return_object ( )

inlinenoexcept

Function called by the standard library when the coroutine is created.

Returns

dpp::task The coroutine object

return_value()
