The documentation of std::future::valid() is ambiguous. Does one have to use std::future::wait_for(), or does std::future::valid() perform the same functionality?
I want a non-blocking way to determine if the future contains a result or not.

6You can `wait_for` with a timeout of 0 and check if the result of the wait is a timeout. – François Andrieux Apr 25 '22 at 19:31
