void override_outcome_exception(basic_outcome<T, EC, EP, NoValuePolicy> *, U &&) noexcept
Overrides the exception to something other than what was constructed. You almost certainly never want to use this function. A much better way of overriding the exception returned is to create a custom no-value policy which lazily synthesises a custom exception object at the point of need.
The only reason that this function exists is because some people have very corner case needs
where a custom no-value policy can’t be used, and where move-constructing a new
outcome with the exception state replaced isn’t possible (e.g. when the types are
non-copyable and non-moveable).
Unless you are in a situation where no other viable alternative exists, do not use this function.
Overridable: Not overridable.
