Returns

Result produced by the wrapped awaitable.

await_suspend()

template<TaskAwaitable A>

template<TaskPromise Promise>

auto uni20::async::TaskAwaiter< A >::await_suspend ( std::coroutine_handle< Promise >  handle )

inline

Suspend using promise-neutral ownership-transfer semantics.

Template Parameters
