Optional and Nullable Improvements #4502

Open aleks-f opened 3 months ago

aleks-f commented 3 months ago

Optional in terms of std::optional
Nullable should be implemented in terms of std::unique_ptr<T>
NullType should be nullptr_t (or at least a static const)
tests

One point of Poco::Nullable and Poco::Optional was to avoid heap allocations, so Poco::Nullable should be implemented with std::optional as well.
